Pitfalls of Projection: A study of Newton-type solvers for incremental potentials
Andreas Longva, Fabian Löschner, José Antonio Fernández-Fernández +3
Nonlinear systems arising from time integrators like Backward Euler can sometimes be reformulated as optimization problems, known as incremental potentials. We show through a compr…
SymX: Energy-based Simulation from Symbolic Expressions
José Antonio Fernández-Fernández, Fabian Löschner, Lukas Westhofen +2
Optimization time integrators are effective at solving complex multi-physics problems including deformable solids with non-linear material models, contact with friction, strain lim…
Implicit frictional dynamics with soft constraints
Egor Larionov, Andreas Longva, Uri M. Ascher +2
Dynamics simulation with frictional contacts is important for a wide range of applications, from cloth simulation to object manipulation. Recent methods using smoothed lagged frict…
