Ansysinc very nice video, thank you. I have some questions: 1. Did you start to use the automatic settings provided by ansys for the mesh just to show how is it possible to reduce subsequently the number of elements by deleting geometric features ( i.e. fillets ) or this is the standard procedure you apply when you mesh a complex model? 2. How can you recognize at glance the second mesh is a better mesh? because of its "tidy" and uniform apearance in the region of bolts? thank you.
***** great video but do you have a means to use the inner volume from the solid stucture ? ie i have a more or less complex structure of the solid and i need to work with the fluid in the cavity. I cant seem to be able to mesh the cavity. I dont know how you moved from the surface body to the inner fill around 7 th min since if i import it in design geometry and then go to meshing and try to mesh it the surface gets meshed. Is there a trick to it ? I m new in Fluent so i cant really get an idea how to work with the fluid inside. A bit of help would be very much appreciated.
how do you make those transitions from hex to prism mesh which you can see at 11:25? I see you didn't use mesh match control, which doesn't work for me because I get an error saying my faces do not share any topology ;|
+Paw Zet This is done automatically by ANSYS Meshing if you use the option to "Form new part" in DesignModeler after you've finished decomposing or slicing your geometry into appropriate sections. Just select all the parts listed in the tree - right mouse click - Form new part. Now when you go to ANSYS Meshing and specify hexa meshes on sweepable parts and tetra meshes on the rest - the interfaces between the two types of meshes are going to be conformal (i.e. shared nodes).
Please, could you explain how did you the descomposition of the fluid domain into several volumes? Did you do it in Design Modeler, or there are any way to do it in Meshing? Thanks a lot.
Hi Myung1987, did you every figure out how to do this? I am having the same problem at the moment as I am new to Ansys. I have modelled my volume but I need to decompose it in and all the options I have tried have resulted in a segregated meshed volumes that ANSYS cannot resolve the flow through. Any advice you can give me would be appreciated. Cheers.
+Diana Munive Let's say you have a rectangular channel that is very narrow and very tall. With the feature number of cells across gap you can tell the proximity sizing function to refine this area (the narrow edge of your channel) until N number of cells are fitted across this gap. So, you could set your minimum edge size to a very low value without worrying that the mesh will be over-refined everywhere.
you can use any cad program. When saving the cad file, save it as STEP or IGES file format as Ansys only understands those file format. Next, open Workbench and drag the module you want eg. Fluent, Mechanical etc. Right click the geometry box and click import geometry and find the file with the STEP or IGES format and open it.

I am impressed with your mesh! Nice job, thank you for the video
I wanted to know how to model the gusset in ansys
Does simplifying the geometry and reducing the node count affect the accuracy of modal solutions?
did you import the drawing from some other cad software e.g. inventor or was the whole shape drawn in ansys?

you can also do defeaturing while importing the catia/solid works file to minimise fillet extents.
Useful, nice presentation. Thanks for uploading.

I am having the same exact problem. you got an answer ?
I used a different geometry. Then i filled the mouth of cavity with a cap that seemed to work for some reason.
Sir can u make a vedio of aerodynamic analysis of winglet in ansys v18
can I have the cad file. It's easy to follow and learn. Thank you
Hello please can you share with me the details of the different meshing methodes you've done in the CFD meshing and thank you
How to set minimum Edge length? You say it is autumatic but it isn't. 2. Proximate & curvature set is usually take ages.
I've imported model from catia and cant use enclosure tool (not active) to make inside volume for CFD, any idea ?
Why I cannot click those buttons to remove the fillet in ANSYS?
How to find this exact geometry in ansys
very nice presentation...thank you very much for that
please make a video on centrifugal pump void extraction. and seperate its parts impeller ,...
Really useful! thanks!
In structural mesh, if i delete filet or fill up gap, will it affect structure or not??
how do you make those transitions from hex to prism mesh which you can see at 11:25? I see you didn't use mesh match control, which doesn't work for me because I get an error saying my faces do not share any topology ;|

Great video matey
Hi, do u have a tutorial on which how i can create a user defined enclosure, and i cannot seem to by the 'by caps' option that you were talking about
Hi,is there any option for reviewing bad elements,,or selecting elements?
What combination of keys are used to rotate a model through mouse + keyboard?

Slice the body using planes.
How to see geometry after meshing
can you explain what is the purpose to change option NUM CELLs CROSS GAP, please

Where can I find this geometry?
Grab cad
Great video
can you provide the geometry file as I am a beginner in learning ANSYS it would be better if I can go thoroughly.
is this better than gambit?
Hey I have a question, using Fluent how do you import that geometry into that program? Did you use AutoCAD or another computer aided design product?
Use solidworks
you can use any cad program. When saving the cad file, save it as STEP or IGES file format as Ansys only understands those file format. Next, open Workbench and drag the module you want eg. Fluent, Mechanical etc. Right click the geometry box and click import geometry and find the file with the STEP or IGES format and open it.
So, have you already figured it out? Can you share the idea?
thanks a lot !
great video
Selection is not very clear, i don't follow very well since i'm learning this with 14.5 version.
Can you please send the cad file
Ah, I have already figured it out, it's slice operation in designmodeler :)
radii, not radiuses ........not to be pedantic :P
