Distorted IGES geometry

Ahmedzeid

I am not sure if this is the most suited forum to open this discussion under. However, I created a simple spring geometry in solidworks and saved it as an .igs file, when I try to import that file in Ansys Mechanical APDL, I end up with this distorted ugly geometry where the volume creation fails. Any pointers on how to avoid such problem?

(Attached are the 3D model and screenshot of distorted geometry)

Don't use IGES to move solid geometry. Use Parasolid.

Thank you for the answer, I can now mesh my geometry and solve my system correctly (See attached mesh). However, my volume plot still doesn't look correct, which causes my code to crash whenever I try to export a screen capture of that plot. Any idea about how I might solve such problem?

Hi Peter,

I have a similar problem because I want to export the IGES file from Mimics software to Workbench but it's not possible. What do you suggest?

Thanks

Amin

@Ahmedzeid Try Mechanical instead of APDL.

@Amin1372 What file formats does Mimics support?

Hi @Amin1372 , It seems, that Mimics can output .*stl file, if so you can use the Spaceclaim and clean the geomentry and maybe you should try patch independent method( Cartiesian mesh) to analyse the parts.

Cheers,

Ram

@peteroznewman I am afraid that's not an option in my case. Isn't there any solution for the parasolid format in APDL? Or a probable cause even that I can look into?

I expect APDL can open a Parasolid file. Check the Help file. I don't use APDL interface.
