And if you notice the shape of the electrodes is rectangular which I don't want. )nI tried to use the commands below to select the nodes but I still get the above errors I mentioned. Please check for an insufficientlynconstrained model.n orn*** WARNING *** CP = 8.531 TIME= 17:55:44nNode 1 on element 1 is unselected. when I run the simulations I got the following errors n( *** WARNING*** CP = 52.094 TIME= 17:18:13nThere is at least 1 small equation solver pivot term (e.g., at the UZndegree of freedom of node 87422).

I am learning everything from scratch to be honest and I think I am missing so many important/essentials commands that I am supposed to execute. Dear,nI tried to use the commands (nsel,CP and others) but I still get a lot of errors and I can not get the simulation done.
