Not converged

hello, 

I want to ask. I have a cantilever beam model and i want to bend it until the moment reaching the ultimate like pict below. But if I add more moment to my model. Why the analysis always said 'not converged'

I use LGDISP in my running.

NINC 1000 in NLPARM

NINT 100 in NLOUT

 

Is there something I could do to reach the ultimate bending moment?

    Did you request PARAM,NLMON,DISP?

    It generates a more detailed output file that can tell you more details about the convergence.

    Also it generates a H3D file with thw attempts made by the solver.

     

    Make sure you always share the .out files in these convergence issues.
