Can you respond to this question.
As I understand it, inertial relief solves for loads when there is an
acceleration ?field?, in addition to the loads.
So , if we have a load with respect to time, and a corresponding
acceleration with respect to time, can we then find a solution for
each point in time, and thus end up with a load solution with respect
to time.? In effect, a inertial relief solution a each point in time,
a mesh?

Isn?t all the above simply the equivalent of a  rigid body dynamic analysis.
