Hello Omar, 

yes, if the part/zone in question is not part of your analysis, you should be able to either delete or deactivate them from your domain and proceed with your simulation.

Alternatively, you can suppress for physics a body in SpaceClaim or Discovery. This way, you can avoid generating the mesh for this zone altogether. Suppressing an object means it will not be included when you transfer to Ansys for analysis. To suppress an object, you can right-click an object (solid, surface, beam, component) in the Structure tree, or select multiple objects and right-click Select Suppress for Physics.
