Hi Tejas,

This error is due to the output blocks, where parts were recalled multiple times.

I organized the parts in one output block. With DEF as the variable you will get all the default outputs and from the time history plot you can select the required output.

Thanks for the quick reply. It was helpful. I have one more query, I am not getting a constant curve for KE and IE during the impact. I am just getting 2 points at t=0 sec. How can I get a constant curve? You can refer attached image for my result. Thanks.
