Errors with complex geometries

Altair Forum User

I am trying to mesh a complex geometry using Tetra and Volume tetra meshing.

Following errors i faced :

1.)Tetra Meshing.

2d meshing (using ''Edge deviation'' and ''mixed'' elements) was ok but during Tetra

mesh, it shows 707 elements failed.

Due to complexity of geometry, i run ''Geom Auto Clean-up'' and equivalenced edge

with 0.01 mm tolerance.

2.) Volume tetra mesh

A ''segmentation error'' appeared and hypermesh crashes down.

Please also understand, due to complexity of geometry, it is difficult to repair

every element.

I am running the simulation using Hyperworks Professional liscence v 13.0

Please help me troubleshoot the error.

Hi Prakash,

Thanks for your answer but as a matter of fact, after deleting mentioned files, i am still getting the same segmentation error with Volume tetra and element error with tetra mesh.

Can you please suggest me any secure link, where i can share the pics.

Please be noted that the component is highly confidential and we already have ''Vertraulichkeit für Einbahrung'' (Agreement of confidentiality) with Altair in Germany/Poland.I hope the agreement will be valid for Altair India as well.

Thanks in advance and a very happy republic day!
