Hi 

I am running a contact nonlinear solution, with two subcases.

First subcase has a SPC  displacement(enforced), In the second subcase the a force is added to the model.

i want the SPC in the first subcase to be continue till the end of second subcase which is not happening . 

can any one help me in this.

    Hi, 

    In my models, I use CNTNLSUB (in the second step). Does it work with you ?

    Hi

    Thanks for the response 

    It works for me .But in the second subcase, the SPC(enforced displacement.) applied in the first subcase is getting ramped down.

    CNTNLSUB Transfers the Stress, strain displacement, ... into your second subcase. If you want to keep the spc active you must activate in the second subcase again. 

    Maybe you can attach so the fem-file ?
