How to identify and split the faces of imported STL models in Spaceclaim？

[dhy19944]

Hi！How can I identify and split different faces when the imported STL model is treated as a whole? I am currently unable to select and define inlet、outlet and wall. I know that the 'Repair Geometry' 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 ‘Volume Extract’ 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? Thanks！
