    Boundary Conditions

    Hi! I'm using Msc.Patran (with Marc solutor)to analyse a tape spring. In the model, the 2 ends of the tape spring are constraint as follow: T1 <0 0 0> R1 < , 0 0> T2 <0 0 ,> R2 < , 0 0>. The boundary conditions are applied on indipendent nodes of MPCs. I must apply rotations at the same nodes...
