Towards anatomical modelling of multiple organs interaction using real time GPU based non-linear elasticity

Finite element methods (FEM) have been used extensively within the field of surgical simulation to describe physically realistic interactions with soft-tissue organs. However, FEMs require researchers to balance computational costs against approximation techniques to maintain adequate performance. We aim to extend previous work in nonlinear FEM implementation with extensions which improve the performance of accurate modelling of multiple organs undergoing deformations.
