Hi,

I want to make an enclosure around a body to get the fluid volume. However, I need one end of the enclosure to align with one end of the body because the front of the body would make the mesh too large. For example: make an enclosure around an aircraft but starting it along the fuselage behind the nose rather than including the nose and upstream air, forget the fact about needing the upstream air for the CFD.

Any ideas how this can be done since we cannot set cushion values less than 0?

Thanks
