  Hello everyone,
  I have to do Force and Moment equilibrium of a rigid isostatic structure with a force and two reactions in ansys apdl. Even if force equilibrium is quite satisfied (with a low error), I'm struggling with the moment one multiplying forces and arm using cross product. I've tried both in global and in local coordinate system. Do anyone have idea of the reason?
  Thank in advance

  FSUM does this calculation. Is that what you are using?

  Yes, FSUM and PRRSOL. The problem is that results are very far from equilibrium
