Hi,

I have incompatible kinematics conditons due to the use of mat/law13. How can I convert part that uses mat/law13 by rbody on wich I can apply initial velocity or other boundary conditions?

Thank you.

    Hello Bill,

    To apply initial velocity or other boundary conditions, you can use a combination of /MAT/VOID or /MAT/LAW1 + /RBODY, and apply the /IMPDISP, /IMPVEL... on the master node of the Rigid Body.

    This example uses a Rigid Body to apply the boundary conditions (RD-E: 0300 S-Beam Crash) but you can also connect the RBODY to a whole part so that it will behave rigidly. 

    I hope it helps.

    Kind regards,

    Guilherme Brandão.
