I am running a Non Linear Analysis.My model converged upto 80% of load....... after it shows  error like the solution is not converged.In .H3D shall we consider the results upto 80% of load?This results are valid?

    Do you have any other error in the out file? Please also attach out file.In attached screenshot it clearly says ' please verify results as they may be invalid'
