Difference in energy at starting point(at 0 ms)

Altair Forum User

Hello everyone,

I am trying to simulate (side) pole impact simulation on the car model. In the energy diagram, I have seen some error at the beginning of the curve.

As shown in figure, due to some reason Internal energy is not zero at the beginning of the curve and there is some difference between kinetic energy and total energy at starting point(not equal). 

I want to know the exact reason, why there is a difference(or error) in energy at beginning?

 

Thanks,

Nisarg
