I'm using HyperFEA with NEI Nastran V10.1 and am getting the following message: "The FEA results file was found, but element forces were not located." It is reading the initial result file "static.els" in fine, but isn't finding the forces in the "static_i.els" file. And, the static and static_i files are exactly the same size. Any thoughts on what I'm doing wrong?
