    Non-linear Simulation of Assembly fails in first step

    Paul Gessler

      Hello to all of you,

       

      I'm working on my masterthesis and I try to model a steel pot. My problem is that the solver is running with a coarse mesh of 25mm but as soon as I set it more fine the solver fails in the first step with the error "no or Zero Pivot" which means in my opinion that some of the FE-elements collapse. I'm not able to create a stable mesh. I tried a lot to create a stable and regular mesh but I can't find a solution.

       

      Could anyone of you please have a look on my assembly and give me some advice?

       

      Thanks in advance!!
