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
jingyuc	4f66d8bb87	update reduced variables and full space position every time applied the force	2021-08-06 17:10:58 -04:00
