  3. I have an initial analysis for which I get a deformed shape. I want to do a subsequent analysis using this deformed shape with some other added bodies. After converting the deformed mesh into a geometry I’m struggling to remesh it in my subsequent multiple body analysis. Is there a way around this?

      The inherent issue is that the technology behind the conversion of a mesh back to a geometry file is still quite young so the final geometry can be of poor quality. There is a way around this by avoiding the export to mesh – convert back to CAD – and remesh altogether by not exporting the deformed shape at all. See attached image. System A has the original geometry you deform. System B has any bodies that you want to add to the subsequent simulation. System C is where you do more deformation of the already deformed shape. This way the deformed shape does not need to be converted back to a geometry and does not need another mesh (deformed mesh is used).
