How to make SofaSphFluid plugin support FreeMotionAnimationLoop ？

[vr3dvr]

Recently I want to use SofaSphFluid in my scene. FreeMotionAnimationLoop is configured in my scene. When I run the example SPHParticleSink_obstacle.scn, I add the FreeMotionAnimationLoop option, but the effect disappears during runtime. How can I solve this problem?

Hi @vr3dvr

I guess you are using FreeMotionAnimationLoop because you need to solve contacts / constraints in your simulation using Lagrange multipliers. Is this correct?

You might need to add some constraint correction in your sph node, possibly UncoupledConstraintCorrection. But I never used the SofaSphFluid plugin with the FreeMotionAnimationLoop.

I will ask other devs and get back to you
