Hi, I am a bigginer in the FEMAP program and I am running a non-linear solution with MSC/MD Nastran to solve the analysis for a blade in winde turbine. I got a fel massage 4551 which saide :
''STOPPED PROBLEM DUE TO FIVE CONSECUTIVE DIVERGING TIMESTEPS.User information:A solution is not possible. Review NLPARM requests and modifyto select a better solution approach.''
I wonder if you have an idea about this problem??? Is there connection with the time step ? or number of iteration?
