I have this roughly spherical part for which I have been asked to determine the radius as a function of load over a small section of the sphere. My thinking was perform a best fit to the deformed nodes.
1) Is there a better way, since I have to do the fit in some external package?
2) How do I get the deformed mesh coordinates? I've looked at the ASCII output files and don't see the node coordinates, but I might not be looking in the right place.
I wanted to expand onlast post because it wasn't exactly accurate. The study.d## file is just the nodal displacements, not the final coordinates. You can export a NASTRAN deformed mesh, which seems to have the nodal coordinates. They are referenced to the World Coordinate System, which isn't ideal for me, so I'd like to export referenced to a local CSys. I haven't figured that out yet. Then I just have to parse out the region of interest.
