    Hi,

     

    in the out file there is:

    *** INFORMATION # 943
     Subcase 1 has NLPARM option while the model is fully linear.
     This will cause unnecessary calculations and additional solution time.

     

    Try running linear static analysis instead.

    Regarding previous activities, I noticed the same. Hopefully, this issue will get resolved under current maintenance.
