Patent number: 11586788Abstract: In one embodiment, simulation systems and methods perform tessellation, on a GPU in a simulation system, of finite element method (FEM) elements in one or more simulated objects using physics solution data directly obtained by the GPU from the solver. In one embodiment, software compiled to run on the GPU can process the raw, native physics solution data to tessellate non-linear FEM elements without requiring preprocessing or ray tracing. In one embodiment, the tessellation can be performed on the fly based on a user's selected view of the simulated objects, and the selected view can be used to select a subset of the FEM elements and perform a tessellation on only the subset. In one embodiment, a level of tessellation can be dynamically determined based on the user's selected view.Type: GrantFiled: July 2, 2021Date of Patent: February 21, 2023Assignee: ANSYS, INC.Inventors: Jonathan Peter Rihan, Viralkumar Patel
