Reply To: Successful explicit analysis

Hi 

Thanks for your informative reply. Here are some details of my model. I have defined gravity load on my tank part (not the pipe or impacter part) by Load_gravity_Part. Second thing is that I also applied damping (2%) in the tank not in the pipe like below:

I also defined Automatic_surace_to_surface where pipe is slave and tank course 1 where pipe is hitting is considered as master with static and dynamic friction coefficients are 0.21 and 0.19. 

There are some gaps kept (small distance) looks like below:

The pipe and tank course 1 where pipe is hitting defined as MAT_003 (plastic kinematic) with strain rate parameters defined. So, this is plot I got after loading glstat:

In my model, I have initial velocity applied to the pipe as 3 m/s. Yes, there are no prescribed motion except Load_gravity_part applied to tank part. 
Another think to mention the termination time is 0.03 sec. Since it is taking too much time. But with that time the pipe hit the tank and rebounded. That I checked. You can also see from the below figure of a node of pipe front.

Do you know what is messing up my results as my energy plots are quite different than yours. Thanks.
