I am doing non linear explicit analysis. I am getting 2 errors . 1st one is input error in material ERROR ID is 740 . It shows as the NFUNCT MUST BE GREATER THAN 0 .
2nd error is
Error in boundary condition definition.Error ID is 678. It tells UNDEFINED NODE GROUP ID=2.
Error ID 678: there are no nodes defined in boundary condition.
ERROR ID 740: there should be at least one function referenced for tabulated material laws.
