+DrDalyO It amazing that how a person take out time for others in this busy world and shares his knowledge with others. Thank you on behalf of my all classmates in uni.
Yes thank you very much for taking the time to make these videos. You are helping people all over the world that are trying to learn and school just doesn't cut it when there are professors that really can't teach. Love these videos and I'm on a video marathon taking in all this knowledge. Please keep making videos. So useful
Thanks Dr.DalyO much appreciated and very helpful video. I used a remote force and adjusted the coordinate system to place the force at the center and got similar results, without having to split the face.
Thanks for your time and effort of sharing your knowledge to the world. Excellent..I'm thrilled every seconds on video, what's new knowledge i can learn.
I will add one byte of knowledge into this fourm and that is Adding cells in the thickness actually increase the softness and make structure little softer then in real life and this is the reason why changing global size parameter to 0.8 increased the stress and deflection because it artificially soften the beam The solution to this is to use not more then 4 cells across the thickness On the contrary using tetrahedron across thickness makes beam stiff and thus artificially reduce the stress and deflection
Hi... have you ever tried to do this FEA with a C channel section? It doesn't work because of singularity issues... is there any soluyion to this kind of problems? Thanks...
Why does your deflection look symmetric when the support you applied have unsymmetric properties? I.E the fixed support prevents rotation. Why are you using a fixed support at all when the beam is simply supported?
It may be a simple question but I was wondering why did you not choose to slice the body in order to apply the load at center. I have thin stacked beam-like filaments that I would like to keep fixed from the center to avoid adding weak springs when I apply moment in the Z-axis. And I thought the easiest way for me would be to create a plane offset to the center of the stacked beams and use the slice command. I realize that this causes the bodies to be separated but if I use the Bonded condition, I hope to get a result similar to a uniform stack of beams ...is this a correct approach?
Hi DrDalyo, please, send me example of simply supported beam under two points loads with span 2400mm and two loads are far 450mm from right and left support and distance between two loads 1500mm
Sir I did not understand the convergence concept.....can u help me out in it??Like i did not understand the relation between the allowable change that we specify and the results we get after convergence....
i have a composite material in spaceclaim and i want to bend test it , should i make the load and fixed geometry and also mesh it in spce claim then transfer in mecheanical model and then direct into structural model updating the engineering data and then defining the loads and force bars in the static structural..
bro, i applied force as you did. but , don't know why the force direction is acting along the edge. if i change direction, force just flips along the edge. how do i change the direction to become perpendicular to the face ? SO, i first applied force on face in downward direction. then, edited it and changed geometry to the edge and its direction remained the downwards.
+DrDalyO, how can we find shear force diagram and moment diagram from this? I know how to do for a line body case. Is it possible here? Or else, is it possible to find avg shear force on a section?
I am facing a small hurdle, why is it that if I set both the ends as fixed and simulate .... im getting inconclusive stress results or any result for that matter. btw, thanks for the amazing tutorials .... I strive on them man :D
I have a question if we apply force by selecting 2 surface then the magnitude of force on both surfaces gets divided into half as of input value on each surface?
Please tell me how to fix this error.."AN unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes".???
Hi, excellent video, I have a question, in my degree thesis I have to place a force that varies in time, as I could put it, I'm doing a simulation of the tension test Thank you
How would I apply a point load at x distance from one end for a 1D beam? I understand how to do this for 3D beams, but not 1D. I've tried adding construction points to my line sketch, however when I go to add a force, it only allows me to select to the two points at the very end of the beam, and the point I've added isn't visible. Reason why I ask for 1D, is that for my assignment, I have to analysis a simply supported beam with a UDL and two point loads by doing 1D analysis first and then 3D analysis and compare the results. Also, can you explain your choice for the supports used? I thought a simply supported beam had a pinned support on one side and then a roller support on the other, however I can't find these support options in ANSYS 17. Cheers.
Hello, how can we download file? I clicked it but can not download... it keeps asking that something is added to Chrome, but even after it is added it does not allow me to download.Thanks.
hello sir, if i import model from another software (creo) like complicated assembly and now i have to apply center load HOW i can split it,or there is any other video, or give any other idea about to add small surface there.(i added in creo but mesh failed in ansys actually that surface can't mesh) so please help me thank you
Dear Dr. DalyO I wonder if you can help to predict the collapse load in a simply supported beam and a cantilever beam by using ansys . Looking forward to hearing from you. Omar
+Galloper What do you mean the collapse load? you mean ultimate tensile strength? that would just be when the stress in the FEA reaches the limit of the material your using. So for example basic steel has a yield at 250MPa and ultimate at 500MPa, so load the model until your stress reaches this value, but if its a simple problem you could just calculate it by hand would be faster. Missing some details here, please give me more information. Thanks for watching!
DrDalyo, thank you very much for your reply, collapse load is the load at which the beam fails. in other words, below this load the still safe,at and may be after this load the beam gonna collapse. I did the analytical solution and I just wanted to verify my results. Looking forward to hearing from you
+Galloper So then it is as i stated before, depending on your materials ultimate limit, it will fail at that point. so if your UTS is 500MPa, and the stress in ANSYS reaches that value, the material will completely fail.
+DrDalyO that was a good point to start with, also I wanna add the following. A structure may completely fail even well before yielding is reached. For some, buckling stresses may well below the yield stress. Thus the users have to calculate the "failing point", which takes into account the all possible failure modes, and compare the stress from ANSYS with that value.
@DrDaylo, I would like to ask that do you have any video in which you have simulated failure of a material when the load reaches the ultimate limit of that particular material?
very useful video. I have a small doubt, How do I check stress on the body at specific point after the analysis, If i use Probe to check the results, I am not able to check at exact required location.
+Pavan Agarwal you can create Construction Geometry, where you can then create lines and planes, from there you can scope results based on lines or planes. If you want just a node or element, using the newer versions of ansys you can click to show mesh, and use node or element selection tools to select the node or element, then create a named selection, and then in results use the named selection as the scope. Hope this helps!
Is this using 3D beam elements, I have to do something similar for 1D beam elements; would these be sketching a line and using a cross section as opposed to sketching a rectangle and extruding?
+Liam Owens yes you could sketch a line and create a line body with an applied cross section, it would give very similar results and use less computing resources. See my video on linear buckling, i believe i use a line body. Also my video on a bridge i believe. Let me know if you have any other questions
+Justin Prendeville good question. No not really. Instead of applying a load, you can apply a "displacement" and then check the reaction forces to get an idea. Or you can do the trial and error but by using "parameters" so it will do it automatically
+akram shaikh good question, cylinder would not be as easy. 1) simplify the problem and use a line body with a cylinder cross section and use similar boundary condition as this video. For how to do this, check my new linear buckling tutorial. 2) add two thin flat square plates at the ends of your cylindrical beam, then apply similar constraints. This should not affect the results near the center of the beam. 3) you can use Remote Displacement constraints on the cylinder edge, say left BC, constrain in Y, X, Z and the right BC only in Y, Z. Not sure of the results but you can play around with using the cylinder edge or adding BC to specific elements or nodes near your support. You might get singularities but you can just ignore them if your focus is near the center. Hope this helps! Thanks for watching. Drdalyo
You could split the face geometry at the bottom to make a line, and then apply a displacement boundary condition making the vertical and lateral condition 0, and only allow for horizontal (FREE). This depends how you set up your axes.
Hello Sir. Thanks for your useful video clip. Do you have a video lesson about analysis Simply supported beam-center load for long-term load? If you know how to analysis please kindly to share, thanks. Best regard!
Hi Sir, first of all thanks for your sharing knowledge, really appreciate it. One quick question, I'm doing exactly the same case as yours but in 2D, thin-shell elements type. I was wondering that would i just be sketching the 2D surface and define the shell mesh in order to obtain less computational time and more accurate result or there is some other change should be made during this method? Thank you
+Piyabut Tangjitmanngamkul Your much better off using Beam elements, not shell. Draw a single line in modeler and then create a line out of it, then apply a crossection to that line (in modeler). So in this case it will be a square section, then apply the thickness/dimensions.
Your model is not correct: if you lower the allowable change convergence percentage to 0.01% you will see that your model does not converge and so contains singularities and so is not valid... please check and let me know your findings
thank you very much for your video it very helpful am from sudan would you make simply supported RC beam am knew to ansys and i couldn't find helper for ansys here in khartoum anyway thanks
+DrDalyO Since there are many people interested in learning how to create the model (geometry) as well, it'd be very appreciated if you could please show step by step in these first videos to get us familiar with ANSYS. Later videos, maybe we can focus more about other things

Best tutorial ever. Thanks x100000000
+Steven Lee np!
this video is very useful
you can select the middle nodes for applying the load without having to change the geometry
Yes! On the newer versions of Ansys you could!
Great Tutorial
Thank you sir!
Thanks mate, for part I too.
Thank you so much!
Welcome!
Really helpful...Thank you man
You're welcome!
but using the cross section over line don't let us to have factor of safety and shear stress. although shows shear forces and max combined stresses
Thank you for another brilliant video, which video should I watch in order to learn how to do a failure analysis?
I will add one byte of knowledge into this fourm and that is
Adding cells in the thickness actually increase the softness and make structure little softer then in real life and this is the reason why changing global size parameter to 0.8 increased the stress and deflection because it artificially soften the beam
The solution to this is to use not more then 4 cells across the thickness
On the contrary using tetrahedron across thickness makes beam stiff and thus artificially reduce the stress and deflection
my professor asked me to find the axial force 3L/4 from the left support. Could you please also explain how to find it?
u r awesomeee..
can we create a crack on surface of any solid with no depth by using face split, will that be correct?
Hi... have you ever tried to do this FEA with a C channel section? It doesn't work because of singularity issues... is there any soluyion to this kind of problems? Thanks...
Hi it should work without issues
Why does your deflection look symmetric when the support you applied have unsymmetric properties? I.E the fixed support prevents rotation. Why are you using a fixed support at all when the beam is simply supported?
Sir,i hav a question that how to draw circle on top of beam below the loading areas..
great work thx so much
alslam alakam
please sir, why the normal stress in the upper compression and lower tension is not equal in magnitude.
When i try to use the split screen to add my force, it doesn´t go vertically even though I selected it with the edge. How do I fixe it?
You can change it from Vector to Components and enter the direction manually based on coordinates
It may be a simple question but I was wondering why did you not choose to slice the body in order to apply the load at center. I have thin stacked beam-like filaments that I would like to keep fixed from the center to avoid adding weak springs when I apply moment in the Z-axis.

Really good video. Congrats. Do you work with plates or sandwich plates?
Hi DrDalyo,
please, send me example of simply supported beam under two points loads with span 2400mm and two loads are far 450mm from right and left support and distance between two loads 1500mm
Please email me about this!
very good
I dont get one thing. When you refinned the mesh, from 10 mm to 8 mm, the results got distance from the analict result. Why did that happen?
nice .... thanks..😍😍
Sir I did not understand the convergence concept.....can u help me out in it??Like i did not understand the relation between the allowable change that we specify and the results we get after convergence....
Sir amazing video...and thank you so much.....
Sir, I have one request that can you make one video on how to do mesh convergence study.
i have a composite material in spaceclaim and i want to bend test it , should i make the load and fixed geometry and also mesh it in spce claim then transfer in mecheanical model and then direct into structural model updating the engineering data and then defining the loads and force bars in the static structural..

SO, i first applied force on face in downward direction. then, edited it and changed geometry to the edge and its direction remained the downwards.
why u don't use the lines creates from points and then cross section is applied to that and results are shown using beam tool
You could do that, it would be a simpler way of solving the same problem. This way just shows you more detail.
@@drdalyo thanks Dr.
I did exactly the same, but when I go to modeling, the edge I created does not appear
Are you doing it in spaceclaim or design modeler?
hi there, good job but i have a question, how can we evaluate the bending angle on the middle of the beam
? and thanks (:
Where can I download ANSYS software please. Kindly share the link
great video! tnx! means a lot! ;)
thank you!
Thank you. Could you demonstrate how to use random vibration ?
+DrDalyO, how can we find shear force diagram and moment diagram from this? I know how to do for a line body case. Is it possible here? Or else, is it possible to find avg shear force on a section?
At center u applied load on line. Is it possible to apply load on particular area of that face sir?
I am facing a small hurdle, why is it that if I set both the ends as fixed and simulate .... im getting inconclusive stress results or any result for that matter.
btw, thanks for the amazing tutorials .... I strive on them man :D
+Sarfaraz Ahmed you should be getting conclusive results, maybe your not setting your fixed support correctly?
I have a question if we apply force by selecting 2 surface then the magnitude of force on both surfaces gets divided into half as of input value on each surface?

Could you please tell me, how to applied point load on the centre of the section ?. Because i need to apply eccentric load on column.
You can use node selection tool, and select the node, right click and create named selection. Then apply the force to that named selection.
Remarkable video.I have a small question.How do i check moment at a specific location.
read the comment of Drdalyo same procedure
Hello, how can we download file? I clicked it but can not download... it keeps asking that something is added to Chrome, but even after it is added it does not allow me to download.Thanks.
Did we have to split the face? why wasn't the offset edge enough to appl the force B.C.?
You could also apply an offset force if you like. I did a split face because it was more visual.
thanks a lot for this video , please can you do analysis and stresses results for tappered I section beam (airplane spar(titanium) ?
Sir..can we apply "pressure" instead of "force" at the top sirface as a boundary condition ?
