Salam, Do you think which one is the best software for creating Hex meshing in FEM simulation?
1) Hypermesh
2) Truegrid
3) ICEM, Ansys option
4) Other software
and could you please explain why??
With best regards;
Shabnam
Dear Dr. Tarkes Dora, Many thanks for answering my questions, Can I ask you one more question?
I use Hypermesh, in this software there are two ways for creating Hex meshing for a complicated geometry. one is dividing the geometry in some partitions (which are map-able parts) and then meshing this partitions by hHEX meshing one by one. the second way is meshing the simple geometry and then changing the positions and locations of nodes in a simple geometry to create the complicated geometry (it is called Hypermorph).
Do you know If ICEM has more than facilities than this??

Dear Mr. Borumand;
Thanks for your suggestion;

Dear Dr. Talebi;
many thanks for answering my question.

Dear Tarkes Dora; Many and Many thanks for your complete answer. and also thank you for your suggested video. actually they are really helpful.
Thank you!
I totally agree with Dr. Talebi. The hypermesh is the most powerful meshing software. It enjoys some advanced tools which help you generate high-quality and high-accuracy meshing structure. I highly recommend that you start learning hypermesh; however, its UI may not be as friendly as the other software packages you have experienced before.
Tahnk you Mr. MAlmir,
It is more than a year that I worked with hypermesh, but unfortunately it's way of meshing is not satisfying for my complicated geometry at all!
These days I go through the youtube videos that Dr. Trtkes Dora suggested, and I guess I must accept that ICEM has better facilities for creating Hexahedral meshing!
Facilities like O-grid, C-grid and L-grid is really fantastic!
I will also choose Hypermesh. It may not be perfect, but it is the best tool I have used. A new up-and-coming software is MSC/Apex. Apex is not as mature as Hypermesh.
Thanks Mr. Wright for your answer, and many thanks for introducing new software! something new!! :)
Salam Shabnam,
Hope everything is going well with you. I have never used Hypermesh, however I think ANSYS ICEM has all the tools and features you need to drive the best quality mesh. As far as I know both are using kind of same algorithm to create Tet mesh and transfer it to the Hex mesh. I think it is not faire to make difference between software!!, because each of them is good for certain application.
Dear Mr. Ahmadimoghaddam; Thanks for replying my question. To be honest by asking this question i want to understand the facilities of these software for creating hex meshing. I want to find the tasks which each of these software sophisticated for. Thank you!
If I understood correctly, you want to know what features are available in each software and what capabilities they have. As I mentioned earlier I have not worked with Hyper mesh, however regarding ICEM I think "ANSYS ICEM CFD Tutorial Manual" document will be a good start to understand how these features work to generate Hex mesh. You can easily find it online.
Many thanks Mr. Zakrea for replying my question! but I am a bit confused. Is Ansys APDL different from Ansys ICEM?
I think the suggestion has been made is not completely reasonable. when it comes to CFD, a quadratic Tet mesh does provide a good accuracy in the analysis. However it depends on the geometry and etc.
What I suggest, start with using mesh module in ANSYS instead of ICEM first and perform your CFD. This module is capable of creating hex mesh including most of the features in order to generate a high quality mesh. Remember you need to choose CFD option in Physics Preference section, otherwise CFD will not recognize it. If you do it this way, you did your analysis and can quickly check your result and see the effect of Hex mesh in your model. I'm pretty sure if you work around with this module, the difference between the result will be negligible. Hope that helps.
I did not get the fact you don't have CFD analysis.
