This paper presents the Long Elements Method - LEM, a new method for real time, physically based, dynamic simulation of deformable objects. The method is based on a new meshing strategy, using long elements. The number of elements per model is proportional to the square of the length of a side rather than its cube as in a standard meshing based in cubes or tetrahedra. The LEM uses an original combination of static (state-less) and dynamic approaches to simulate deformations and dynamics. Global deformations that conserve volume and are convincingly compliant are obtained. Models are defined using bulk material properties. The method is particularly attractive for soft tissue modeling
