Default Meshing of split volumes

Hello all,

I have a complicated 3-D geometry which I meshed with Hex-Cooper after splitting into several smaller volumes (which are connected). Can I export the mesh for all these volumes at once or do I need to export the mesh for each small volume independently and then merge them in Fluent?

What if some of the volumes have tet mesh and some hex-cooper. Is it any different?

Thanks.

Dhananjay

You can export the mesh for all the volumes at once whatever types your grid-net is composed of.

Sincerely, Jinwook

Thank you Jinwook,

A follow up question. Is there any step I must perform in fluent when I am reading a mesh which consists of multiple volumes? I tried a simple test case. I seem to be getting different results even for simple volumes when they are split and sent as opposed to when they are sent as 1 volume.

Dhanjay, when you export a *.msh file from gambit and read it into fluent, it no longer contains geometric entities (i.e. faces, volumes etc), it is basically the discretised domain. Perhaps the problems you are getting are due to splitting volumes in gambit. One tip is to make sure your geometry is complete before meshing (also, export geom as an Iges and read back into gambit, then all numbering etc is in order). When you split meshed volumes you have problems with the links, maybe your mesh is changing every time you split volumes, and so your solution is different.
