Hello all! I imported an .inp file model which was converted from another .am file into Abaqus. This model (model 1) doesn’t include any geometry information but only has 3D finite element model. I want to create an air model (Cube) surrounding model 1, subtracting model 1 from air model and leave a hole whose shape is the same as model 1. Then I want to insert model 1 to the hole again and compute acoustic problem. The question is: I can’t use ‘cut/merge’ function in Abaqus because there is no geometry information in model 1. Could someone tell me how to do that? Thanks very much.
