steps returned been computed. Predicted solution The solver computes the initial guess for the new guess leads to parameter value based on the solution for the undefined function previous parameter value. This initial guess led to value an undefined mathematical operation. Try using another Predictor on the Parametric tab of Solver Parameters. Repeated error test During a time-dependent solution, the error failures. May have tolerances could not be met despite reducing the reached a time step to the minimum value allowed. singularity. Returned solution The solution returned by the stationary solver is not has not converged. to be trusted. It might, however, be useful as initial guess after modifying equations or solver settings. The elasto-plastic The Newton iteration loop for the computation of solver failed to the plastic state at some point in the geometry did find a solution not converge.
