[Other] How to generate mesh only in fluid domain

quinette · April 8, 2013, 05:59

Hello

I am new to ANSYS.

I have an enclosure (fill with air) outside of a complicated mechanical assembly (solid).

I want to model the air flow outside the assembly.

Can anyone tell me how to generate mesh only in the fluid (air), instead of meshing in the the whole region of fluid + solid ?

Thank you very much.

your model is 2 D or 3 D

It is a 3D model

it is very easy.
make the assembly hollow. set the surface of the assemble as a boudary face.
