Keep a “Nastran debugging journal” – log each error code and how you resolved it. Over time, this becomes your most valuable reference. The most advanced tier
Single Point Constraints (SPC) lock a grid to ground. Multi-Point Constraints (MPC, RBE2) tie grids to other grids. Tutorials often use RBE2 elements to represent "rigid bolt holes," which artificially stiffens the model. Over time, this becomes your most valuable reference
Platforms like The Engineering Lab offer deep dives into custom result generation using Python or Matlab.
