This document covers the implementation details and challenges/questions for the integration of the BETA version of NVIDIA's FLEX as one of the physics simulation subsystems. FLEX is able to perform high-fidelity, real-time mutli-domain simulation of fluid dynamics, aerodynamics, elastic and inelastic collision, gravity, deformation, and phase transition effects.

Goals:

  • Integration of FLEX into Simulation project
  • Collision detection and resolution using FLEX for inelastic collisions between simulated objects (e.g. planetary gravity + object)
  • Fluid simulation
  • Gas simulation
  • N-body gravity

Extensions:

  • Can we use the FLEX fluid physics simulation to provide more accurate aerodynamics models (w.r.t. drag/lift forces) than traditional aerodynamics sims like JSBSIM?

Questions:

  • How easy is it to get information about the simulated objects back? E.g. for sensor and actuation data?

Unresolved Issues:

  • Currently requires NVIDIA GPUs
