Direct Position-Based Solver for Stiff Rods

Crispin Deul, Tassilo Kugelstadt, Marcel Weiler, Jan Bender In this paper, we present a novel direct solver for the efficient simulation of stiff, inextensible elastic rods within the Position-Based Dynamics (PBD) framework. It is based on the XPBD algorithm, which extends PBD to simulate elastic objects with physically meaningful material parameters. XPBD approximates an implicit […]

A Physically Consistent Implicit Viscosity Solver for SPH Fluids

Marcel Weiler, Dan Koschier, Magnus Brand, Jan Bender In this paper, we present a novel physically consistent implicit solver for the simulation of highly viscous fluids using the Smoothed Particle Hydrodynamics (SPH) formalism. Our method is the result of a theoretical and practical in-depth analysis of the most recent implicit SPH solvers for viscous materials. […]
