Nonlinear solver failed to find equilibrium

lemontree · 2024-11-03T06:50:07Z

I have set up CNRBs at both ends of the box and applied rotation around the y-axis to these two nodes via the boundary prescribed motion node, I want to get to the moments at the two nodes. The help manual mentions that "prescribed motion" can only be done by implicit analysis, but my calculations appear to be" Nonlinear solver failed to find equilibrium." Suppose I want to use explicit analysis, is there another way for me to apply rotation to the CNRB nodes

Gotcha. So you were able to solve your problem using *Boundary_prescribed_motion_rigid? Or do you also need to change your CNRB to constrained extra node?
