Decoupling simulation accuracy from mesh quality
For a given PDE problem, three main factors affect the accuracy of FEM solutions: basis
order, mesh resolution, and mesh element quality. The first two factors are easy to control …

Determining predictable strike points on tossed objects: A 2D physics simulation approach
Catching flying objects is a significant challenge for humans and robots, particularly when
the physical parameters of the objects are unknown. Humans often strike incoming objects …
