SubscriberI have a four layered structure on to which I have to apply a prestrain value at 350K and then I have to cool it to 300K and then to 77K.
So when I applied the prestrain value and tried to solve, the solver doesn’t converge. I thought it might be due to the initial prestrain value Iam giving. So what I did was I tried to give the prestrain value to the materials after making the contact pair kill in the first step. Then on the second step I made the contact alive. The solver solved the problem. But the issue is in the result. I cannot see the prestrain value in the initial step.
the prestrain value given was
inis,set,csys,-1
inis,set,dtype,epel
inis,set,mat,1
inis,defi,,,,,2.4455e-3,1.9427e-3,-2.2588e-3,2.4455e-3,1.9427e-3,-2.2588e-3,2.4455e-3,1.9427e-3,-2.2588e-3
inis,set,mat,2
inis,defi,,,,,2.064e-5,1.2734e-5,-1.4897e-5,2.064e-5,1.2734e-5,-1.4897e-5,2.064e-5,1.2734e-5,-1.4897e-5
inis,set,mat,3
inis,defi,,,,,-1.4764e-3,-9.1691e-4,1.0269e-3,-1.4764e-3,-9.1691e-4,1.0269e-3,-1.4764e-3,-9.1691e-4,1.0269e-3
inis,set,mat,4
inis,defi,,,,,2.6127e-3,2.0345e-3,-2.3917e-3,2.6127e-3,2.0345e-3,-2.3917e-3,2.6127e-3,2.0345e-3,-2.3917e-3
The kill and birth command I given was
esel,s,type,gcn,
ekill, all
allsel
Â
esel,s,type,gcn,
ealive, all
allsel
Â
I really want a help to proceed , please help
