Large Extarnal Model

Hi all,

I checked more than 30 posts for my project however could not solve it. I have a large lattice model that can be import as OBJ or cdb file, and also, I want to add more part with different material.

1) OBJ to Solid body

Because of large facets body, I can not convert it solid body nor use auto skin command. I want to analyze it as a shell element. I dont use student version.

2) CBD

If I import it as a cdb file, I can not define contact with other parts. When FE mesh is exported from lattice generator program, node sets can be defined and imported to ansys, however, I can not use these named selection to define contact with mesh generated in ansys.


Could you show me a way to analyze these large facets body? Almost I send two months with old post and videos but I have not figure it out.

    Thanks for your patience, how are you bringing in the cdb file? Is there a way in the lattice generator program to export the faces with named selection? Because if one writes a cdb from APDL with components, those are imported back in Workbench via external model.

    Hi Aniket thank you for your reply,

    i) Lattice Generator program can also generate FE mesh and export it as a cbd format ;however, the program does not let me to clean intersect or sharp edges.

    ii) Yes, Name sections can be export as a nodes. However, I can not define contacts to this named selections.

    I try to use auto skin command and then clean the inadequate faces with spaceclaim, but I can not remove all the small and inexact faces.

    Should I use different MESH generator rather than spaiceclaim ?
