Hi,
What will be the influence of inertia when we are employing advanced mass scaling on the models? I know that there will be no added mass on the model ( even for a higher time step). However the acceleration is dependent on the time step. So there will be a change in acceleration with increase in time step and effects force ( F= M*a). And it is evident in my results ( I'm performing frontal crash simulation of a car with 1 million elements) that there is a change in acceleration curves as I overlay it with no mass scaling / conventional mass scaling. Can you explain me the reason behind it?
