I imported an FEM model from a .dat file that contains PSHELL, PBAR, PROD ecc. All the material properties are properly defined (there are a bunch of MAT1 and some Mat8) and they all have density. I added a couple of SPC and set up a sol 103 to check if any component of the model is loose. When I launch the analysis it fails immediately. I have all the properties correct (including density) and the model is overall small (260 CQUAD4). I set up a similar analysis last week for another model and run with 0 problems. I'm trying to run sol103 with EIGRL card
Any idea about what kind of checks I can do in this case? I have absolutely no clue on how to move forward
