Equivalent of iMesh_getEntsByTagsRec?
by James Porter 20 Jun '11

20 Jun '11

Does CGM have an equivalent to iMesh_getEntsByTagsRec and iMesh_getEntSetsByTagsRec? These are necessary to support iRel_changePairType and iRel_changePairStatus. - Jim

Hi, Hong-Jun I am now working on OCC performance issues, and did find that attribute save takes long times, and I am still working on a fix for it. Give me one more week to see if I have any clue on it while you are thinking about using ACIS, and I'll let you know how OCC can do on this matter for you. Good luck!

Use ACIS classes and api functions through CUBIT
by Hong-Jun Kim 10 Jun '11

10 Jun '11

Hi, all I am using OCC geometry kernel for parallel meshing, but it takes too long time to import and export large size of geometry with attribute information. For example, it takes over 1 hour for merged "vhtr" geometry(327 bodies) to be distributed to processors. This makes our parallel mesh tool not so practical in real world problem, then I am thinking use ACIS kernel instead through cubit library. For this, I need to use some ACIS classes and api functions such as "BinaryFile" and "api_save_entity_list_file" and then, is there any way to use these from cubit library? I am wondering if I can make and use some dummy header files similar to "NoAcisQueryEngine.hpp" to solve this problem. Thanks. Hong-Jun
