Is this correct way of volume extraction in discovery aim?

      The simulation is to study solid-fluid interaction and the volume extracted is for fluid region (3D).


      The after volume extraction, a cross section of the model looks like fig(a).


      When I hide one of the component(for example a screw head,on left of fig(a)), it looks like fig(b). The volume-solid(purple area) is covering the solid screw area as well. Is this volume that is extracted correct ?


      (Note: Both the figure a&b are part of a bigger geometry)

      Hello lakshmidnair99


      Did you display all the bodies while extracting fluid volume? It could be possible that the screw head body might have been hidden during the process.


      In Structure tree, expand the "Volume" component (created after volume extraction), then right click on the Volume body and select "Update volume body in context". This will subtract the the screw body from the fluid region.

      Hallo,


       


       'update volume body in context' did not work. However, capping off few regions helped. Many thanks for your timely assistance.
