Hi guys,

Just a very simple question.

I have a prismatic domain with a prism inside it (see picture). I want to mesh the volume of the domain without the volume of the prism. I make a material point for each one of the volumes but when I mesh it ignores the inside prism volume and mesh all the domain. I have the option "mesh internal domains" disabled in the volume mesh menu.

What I do is:
1) Create surfaces that close the big domain.
2) Create material point for that volume
3) Create surfaces that close the internal domain.
4) Create material point for that volume.
5) Mesh surfaces (ok)
6) Mesh volumes.

What am I doing wrong? I've done this many times before but this time it isn't working.

Why do you have a material point in your inner domain at all? Deleting it should do it.

I don't know if I get it right, but if you set the body of the internal prism to "Add Frozen" and your fluid domain to "Add Material", you can remove the internal prism with a boolean operation with the solid as tool body and the fluid as target body. Then, you can preserve the inner prism as you wish and suppress it in meshing if you don't want to have it meshed.

That didn't work. It just ignores the inner domain. It's so weird.

I upload my case and geometry files in case you want to have a look.

How do I do boolean operations in Icem? Thanks!

Dude, your inner box is missing one complete surface. See attachment. So it is no wonder that the box is ignored. Create surface from curves, delete solid body and you'll be fine. You can not do boolean in ICEM as it is surface based.

Oh my, what an stupid error! It seems I was too tired yesterday!

Thank you, Kad!
