Optimizing simulation performance



  • What are some recommended tweaks to the Simulation and Physics settings in ANVEL 2.0 to improve ANVEL performance when simulating more complex (many axles) vehicles? First and foremost, I am looking for real-time simulation, even if it comes at the cost of VTI and physics accuracy.

    @rr, there are a couple of approaches that you can experiment with:

    1 - Reduce the complexity (number of contact joints) of your vehicle model. In the past, we've made some of the wheels on multi-axle vehicles smaller (or you could just remove them) so that they don't touch the ground and add to the complexity of the physics simulation.

    2 - Change the Simulation TimingMode to Direct. This will do exactly what you're looking for; sacrifice physics fidelity to maintain real-time performance.

    3 - Try using the ODE Quick Step method (Physics > StepType = Quick Step). This is a much faster, but more error-prone physics solver. It is also possible to bump up the Iteration Count property with the Quick Step solver, while still maintaining faster performance compared to World Step (try an Iteration Count of 10 to start).

  • Great, thanks!
