    Warnings in Nonlinear analysis

    Mustafa Bgr


      I am doing a nonlinear simulation under cyclic loading. But during analysis in warning part of  progress window it is written " Assembled stiffness matrix has negative diagona increment" and in "step number 6", the analysis stops progressing. By the way results are shown and I don't know how valid they are. What can I do?

      Thanks in advance
