Barrier-Augmented Lagrangian for GPU-based Elastodynamic Contact
We propose a GPU-based iterative method for accelerated elastodynamic simulation with
the log-barrier-based contact model. While Newton's method is a conventional choice for …

High-Order Continuous Geometrical Validity
We propose a conservative algorithm to test the geometrical validity of simplicial (triangles,
tetrahedra), tensor product (quadrilaterals, hexahedra), and mixed (prisms) elements of …
