Re: Partition and grouping leaving out faces

Posted by Nejc Jurkovic at March 25. 2019

I have a STEP assembly which I explode to solids and make a partition of them for a heat transfer study.

I create volume groups on partition volumes first and then face groups from the former.

However, on some solids, face are being left out for no apparent reason. Am I doing something wrong, is there something wrong with geometry (checked everything in multiple programs and no problems) or is this a bug? Check the attached screenshot - the marked faces are missing from the face group but not from solid/volume group.

Any ideas/suggestions?

Thanks!

Hi

I create volume groups on partition volumes first and then face groups from the former.

If you created face groups from volume groups, while some of faces belongs to non volume (judging by the image), it is natural that those faces are missing from the groups.

Is there a better way to create face groups on solids?

Face groups are to be created just the same way as volume groups, i.e. on the partition.

FYI, in the end I couldn't get it to work so I chose a different approach:

  1. import STEP assembly
  2. explode it to solids
  3. create a partition from solids
  4. assign volume groups
  5. mesh the partition
  6. create submeshes on volume groups
  7. export submeshes
I avoided creating face groups and it seems to work OK for the geometries that were causing trouble.
Thanks for help anyway.
