jingyuc	a56ce358f3	reduced dofs and interpolated transform needs to be updated from the time_n states in the iteration	2021-08-09 12:43:59 -04:00
jingyuc	0acf18f246	need to update the rigid frame every time when the impulse is applied. reduced external force needs to be zeroed in every iteration.	2021-08-09 11:23:52 -04:00
