Error while applying concentrated load

Hi,

I am testing quasi static tensile testing with radioss explicit. I am trying with imposed velocity, imposed disp as well as with concentrated load. Imp vel and imp disp type gave good results, however the run with the conc. load is failing at the initial stage. I created a rigidbody and gave all the nodes in it over which forceacts. I picked the master node of the rbody and applied load. 

The error ID I get is 207, which says max. energy error reached.

This happens at the contact interface, which I defined for all the components with type7, a global contact.

Any suggestions be helpful. Thanks!
