Problem with having continuous volume in 3 separate bodies
Hi All,

I have imported a part as an iges file into Designmodeler and using the enclosure method i extracted the volume but it extracted three separate volumes and when i proceed to ansys meshing i am getting three separate material region for my fluid flow. How do i merge them to get a continuous flow of the fluid in the entire domain? Is there a way to have them extracted as a single unit? or to merge them to become a single unit?

Thanks in advance for your help.

You can probably merge them as a single volume, but I am guessing that what you really want to do is create a multi-body part...

In DM, Select all the parts in the tree (hold down CTRL for multi select) and then right click to form a new part.

This multibody part will be meshed with conformal mesh between the parts.

Hi PSYMN, and thanks for the response to my question. I was able to figure out that i had to do what you suggested. I would guess you have worked with ANSYS Design Modeler alot? What does the freeze command do? I am using it but i'm not sure why?

Cheers! Jimmy

Freeze prevents the new bodies resulting from new operations from merging with the frozen bodies...

Personally, I don't like the paradigm, but I have learned to live with it.
