Internal Programming error in Optistruct
Hi,
I am get the below error while simulating in Optistruct, This is the first time I am getting this error and I am not able to figure it out, Kindly give me a solution. I tried all the iterations regarding this issue from altair forum , I am using 2017 version, cleared all the temporary files, element count =1166221, Hexa elements, Using NLSTAT with material and contact non linearity and pretension loading.
Starting load increment 1 Current increment 5.0000E-002
Subcase 1 Load step: 5.0000E-02
