Result error

Hi.

My model is RC column connected to RC beam. Boundary condition is applied at the base of beam ux=uy=uz=0, and cycling lateral displacement is applied at the top of column. Moreover, stress is applied on the top of column surface 4MPa. The statically applied step is from 0s-1s stress applied and from 1s-6s lateral displacement applied. After running, messages show. The unit used is tonne, mm, N.


  1. "Solver pivot warnings or errors have been encountered during the solution. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues. Check results carefully."
  2. "A solver pivot warning or error has been detected in the UX degree of freedom of node 1532 located in Line Body. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues. Check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window."
