Atom Posted January 23, 2017 Share Posted January 23, 2017 Hi All, I am trying to speed up my flip fluid sim and when I look at the performance monitor the clear culprit in my slowdown is the Gas_EnforceBoundary node inside the FLIP solver itself. I have one static collision geometry (terrain) and one deforming collision geometry (character). I have "pre" prepared a VDB version of my terrain as a proxy volume. Is there anyway to speed up this Gas_EnforceGemetry node? When I allow editing of FLIP solver contents I can see that the Gas_EnforceBoundary node has an OpenCL toggle. But even if I enable this, I experience no speed up. Even at higher separation rates, like 0.08, I still experience very slow sim times.

LaidlawFX Posted January 24, 2017 Share Posted January 24, 2017 Dive down to it and bypass it and see if it changes your sim. I've had some good luck with that. Quote Link to comment Share on other sites More sharing options...
