I am currently unable to select and define inlet\u3001outlet and wall. I know that the &#8216;Repair Geometry&#8217; command of ICEM can automatically recognize different faces of STL models. Does Spaceclaim have a similar command? As I need to perform fluid structure coupling, I must obtain the internal fluid domain using &lsquo;Volume Extract&rsquo; command based on the inlet and outlet of the STL model in SC. Is there any method to identify these different faces? Also, since I use meshing for mesh partition, is there a similar command that can achieve this function after importing the STL model directly into meshing?
