Non-convergent nonlinear iterations

Recommended Posts



I really need your help.


whenever I implemented OPTISTRUCT, I got " Non-convergent nonlinear iterations for subcase 2" result.


I set hyper-elastic material, and pshellx for 2D design.


Also My load collectors are, SPC/LOAD/TABLED1/NLOAD/NLPARM, and I set load step NLGEOM


I don't know why I couldn'y get nonlinear analysis result in OPTISTRUCT.


My material is the example of MATX62.. I attached My entities and NLPARM screen-picture too






Please give me some advices



Thank you, 


Best Regards,
