conversione catia v5 - ansys

[Ragsta]

importing in ansys an iges file saved by catia v5 I find a geometry different from what I previously saved.
as you can see from the attached images the iges in ansys reports a part of the tube that in the catia file I had deleted.

I searched for some information in the old posts, but not being able to use other softwers like icem (I have these in the company), I don't know how to solve the problem.


please help me!!!

ps place 2 pictures to clarify the problem. .

Thanks again

...all imports I make them through the step format. or even very good is passing through parasolid, but you should lean on auqlache other software cad, because catia does not export in parasolid.

the problem is that ansys often does not recognize the cutting curves of trimmed surfaces.
Sometimes it's just about changing tolerances. (I don't know how why I haven't used ansys for years!).
you can also try to retrimulate the surfaces inside ansys, importing apart as iges the contour curves.

thanks for the answers

the problem remains that the .step is not accepted by ansys and passing through the parasolid would imply using other programs then licenses and therefore money that now there are :36_1_4:

Trimming directly into ansys could be a solution, now I try and let you know.

I very often to do this preparatory work of the surfaces use rhinoceros, maybe you have a license in the company, the cost of the license is really low.
in case you have it you can try using the srhink trimmed surface command that reduces the trimmed surfaces to their possible limit. (the trim in general hides the trimmed part and leaves the intact surface).
is very useful (rhnoceros) to do the preparatory work of cleaning and cutting the surfaces and then make a shell model. work that with a parametric software is often difficult.
I specifically use it to then pass geometries to patran, but in the past I used it with excellent results also with ansys.

...to me it matters it quietly in step, I don't know if it is related to a license issue or is linked to the imported packages installed, because in the installation phase it seems to me that there is an interface in which it makes you choose which packages to install. . .
