We're trying to extract bending and forces from a VIV piping model using Modelname_EIG.txt via editing the autopipe.ini file. However, the process seems to work but the file doesn't contain any useable values (all are zero), apart from the frequency output in the first couple of lines. I've tried changing code to activate axial loads but that doesn't seem to work, the piping has bends in it and the modal analysis work and outputs the mass normalized results ok Any ideas Jon
