FEANIM (Finite Element ANIMation) is a software package to simulate the dynamic
interactions among rigid and deformable objects by using the finite element method and
computer animation technique. Collision response and fracture are two main issues
addressed by FEANIM.
The unique features of FEANIM include:
(1) Two types of interface elements are proposed to simulate the interface between
different objects.
(2) Three algorithms (at different granularities) have been proposed to simulate the
impact behaviour of objects when they collide each other.
(3) An incremental and iterative step-by-step time integration method is devised to
describe the dynamic behaviour of objects.
