I have a model in optistruct made of CBAR elements for size optimisation. The structure is constrained at the base (6 DOF) and has loads at the centre of rotation and on the surface of the structure.

My optistruct analysis gives me Error #312 for each of my loadcases wherever I apply loads ....................any thoughts?............... anyone like to take a look at my model and make some suggestions?8-[
