Analysis runs for hour and doesn´t make much progress

Hello to everyone,

 

i have a problem with an nonlinear analysis. I don´t know if i made some mistakes in the settings or something else. The analysis runs for hours and doesn´t make much or no progress. All other simulations run much faster, few seconds or minutes (other modells were a little bit smaller but not that much). Can anyone tell me if set nlparm or something like that in the wrong way?

 

Thanks a lot.

    Hi,

     

    can you share the solution?

     

    The model did converge reasonably fast using small displacement, however a warning about exceeding  the limit of small deformation theory was reported due to large strains and rotations. It seems this model could be solved more efficiently using explicit (Radioss).
