What displacement method should I apply to the free end for bending? I tried to apply a restraint on the free end with reference to an axis and a 1.5 radian (to make the free end rotate 90 degrees about the axis), but it didn't quite work. It keeps prompting to turn on large displacement flag...
Am a newbie to Cosmos and want to perform a 90 degree bend on a straight extrusion to evaluate the stress or distortion at the inner radius (if any).
Besides fixing one end of the extrusion, I am not sure which other restraint to apply to perform a 90 degree bend?
Please advise.
