great job, thank you very much for sharing. For your information, I repeated this simulation with version 2023 R1 and the idea provided in tutorial works. Results are however slightly different - in the first phase it is almost identical as Ansys Inc., then, after reaching peak force reaction the softening happens faster (results go belowe experimental curve), however it is still satisfying. I will play later with analysis settings and check the correlation. Thanks once again!
@@abhishekbv8740 If you are using explicit, just use Body Interactions -> Reinforcement. That will assign the contact of the rebar to the concrete. If you are using static structural, highlight all the line bodies in the geometry and change the type to reinforcement. I believe he does this in the video
@@abhishekbv8740 if you look at 3:47 of this video, he changes the model type of the rebar from beam to reinforcement. This model is static structural. If you are using explicit, you would use body-> interactions reinforcement and apply to all bodies
Thanks for your model, it's really inspiring. I've one question: ¿is this model able to simulate cracking and crushing? It seems that Drucker-Prager concrete is a kind of plastic material since there's not a decrease in its stress when tension strength is reached. What I mean is, is there a way to combine steel reinforcement (via REINF264 elements) with cracking-crushing concrete (via SOLID65 elements with CONCRETE model)? Thanks in advance and br!
I love your tutorials. Your tempo is sometimes a little too high to really follow it in real-time and some more explanations with some choices of parameters would be nice. But still, I'm learning a lot here.
one question though , if i draw the same geometry in autodesk inventor , while exporting to to the ansys i have some trouble like several bodies of the parts dont show up and show up as a single body = . i dotn wanna draw in spaceclaim , do i have any choice now ?
I dont use inventor so not sure but you can just export your model from inventor into spaceclaim (.stp or .sat) and then fix the geometry up in spaceclaim. Spaceclaim is a direct modeler so can handle anything really.
@@drdalyo i m pretty good with inventor . i dont wannt spend more time again learning spaceclaim, like u said i could fix the geometry in spaceclaim to a imported stp file , ill have a look around . tnx of rthe reply
Quite a Detailed video. Question: Did you model the rebar as line bodies? How did you create multiple stirrups? Was it using the pattern command in spaceclaim or there is any other better method? Can you share your space claim geometry for clearing other geometry related doubts ourself?
The geometry file is in the description below! you can download it. I created it using line bodies and then using the linear pattern features to copy them spaced out.
Very well explained. I tried to recreate the model and managed to run it without any error till 50th iteration. It is showing some error after 50th iteration saying cpu time exceeded. I tried with turing large deflection off and managed to run till 62 iterations. Still I'm able to see partial results. I have some other doubts too. Can we use CPT215 with tetrahedron elements? I saw Drucker-Prager Base model in Engineering data with Uniaxial Compressive and Tensile strength and Biaxial compressive strength. Can we use it instead of the code ?

Hi, thanks for the video. But when I selected the "beam" and clicked on "Assignment" the following message appeared "The shared license is currently not available for this application." What should I do?
Ansys employee response: I can confirm that this workflow (CPT215 and inbuilt reinforcements in Mechanical) does not work anymore in 2021 R1 latest rel.. Thus one would need to use 2020 R2. I should add, that this method is wrong so do not use any of this and ignore that video as it is not from us. So CPT215 elements can be used with REINF elements, but we can not have solid186/187 then use ERIENF/REING264, and then EMODIF solids to CPT215 - that is not correct. If we want to use CPT215 with RENIF and reinf264, then that should be done as in our TD54 example in our help manual (concrete joint analysis). So just emsh with CPT215, and use reinf (this is only done now in apdl).

How to make a model of beam and column reinforcement in ansys?
Can someone explain to me how to interpret RW “split weight factor” color plot shown in this video? What does this represent?
Thanks. What should we do in version 2019 which has not the reinforcement item in model type?
Thank you ... How can i add crack/crush diagram to the results ?
You cannot using this method. please see my other video tutorial on this ruclips.net/video/h2BApwflt3E/видео.html
Hello Dr. Could you please help me with analyse of reinforced concrete column?
Import model from revit or AutoCAD?
Thank you!
Hi sir, do you have a tutorial on fire analysis of concrete elements? Thanks
Hi. How to test the beam to column connection until it fail? Should i use explicit dynamic?
I tried this reinforced concrete beam.but I analyze the solution is not connected between the reinforced and concrete.y
Hey, have you stopped making videos? Hope you are doing well, waiting for your news
Can you please tell how to bond concrete and steel after assigning material?
What time do you need to run this model? Can you share the computer specification that you used?
I believe less than 15 minutes. I have a 6 core processor, with m.2 ssd, quite fast!
Hi, I am using this DP model and the parameters given by you for my model under reverse cyclic load. But, the DP cap plasticity doesn't converge for a particular element. Thus, ANSYS stops. And no plastic strain has developed till now, so could u please help🙏🙏
Hi! Its seems to be an issue with newer versions of Ansys (2021). If you can downgrade for now until I find another solution.
No, even I am using ANSYS 2020R2, with monotonic loading, your model works fine but with reverse cyclic it's giving error
How we can find the cracks in concrete in ansys 2024 workbench and what are the codes should i used?
Sir...... A message of "an unknown error occurred during solution" will generate at the end so what to do sir....... Pls help me sir....
You must use the same version of ANSYS 2020 R2. There are reports that newer versions of ANSYS no longer work with this tutorial.
@@drdalyo Kindly, are there any lines of code (commands) that we can use to tackle these version-related errors?
It worked for me.
Anyone please explain to me what happens if i do not use the command line: RCC=matid. Thanks in advance!
I believe it wont solve
@@drdalyo The command line: RCC=matid or DVD=matid, RCC or DVD is not important, just an alternative letters. I think the command line means that just concrete material model is changed, other materials is not changed. Do you think so?
can you give the neutral file format
Hai, I am using an i5 intel 10gen with 8 GB ram and an SSD and 2GB graphics on my laptop can u suggest which Ansys version should I use.
2019 work with me
