Hello - I have a 3D frame / model with only 4 bars and 2 supports. I am trying to run the analysis as Static but when I run the calculations it switches and runs as non-linear analysis instead. Please can anyone help me understand why this keeps happening to me, I would greatly appreciate it. Please see the simple model file attached.
