This might not be the best place to ask the question but I have to start somewhere!
I have been trying to create/calculate the RMS stress result in the response simulation module with a "large" number of elements (~5500 shell mostly) and I am getting an ''Inadequate spectral line spacing' error, see attached. Changing the evaluation method as suggested in pop-up window makes no difference. It was initially set to "Automatic" so expected Nx to swith to the appropriate method but to no avail. It's not working!
