I am trying to apply a pressure to the interior of a pressure vessel that has been meshed with 3d elements directly from the solid body. I did not use the 2d surface map method to achieve this mesh as it led to issues retaining part geometry when then translating it to a 3d mesh. When trying to select the interior elements to apply the pressure to, I am using "by faces", however this leads to hypermesh freezing instantly (as detailed in the "by faces" section of the hyperworks docs, selecting by faces isn't recommended for lots of elements). Is there another way to select all the elements on the interior of the pressure vessel to apply this load? Or maybe create a set of elements that are considered "the inside" of the vessel based on the list of interior surfaces in the geometry, I'm afraid I can't provide the model
thank you in advance
