[DesignModeler] Generation of fluid domain from solid domain by subtraction

RAJDEEP · November 12, 2019, 05:56

hello everyone,

I have complex internal geometry (mostly tubular structure) through which fluid is flowing. The solid geometry is already modeled in solid works.

Is there any way to create fluid domain which present within the solid geometry?

Currently, i am carrying out the same work in selecting all surfaces then using fill option in design modeler, after calling the solid geometry file in Ansys from solid works.

Thanks in advance

You're on the right track. Instead of selecting all of the wetted surfaces and using Fill to build the fluid domain, use the capping surface option in the fill tool instead.

See this video tutorial. It covers both methods (capping surfaces and cavity). Method you want starts at 1 min in.
