  • FlipSolver2d

    A 2d Flip/Pic solver implemented in C++ following "Fluid simulation for computer graphics" by Robert Bridson

    • Is that normal for FLIP to explode like this? What mistake in implementation might cause this? My understanding is that with more substeps FLIP updates accumulate more and more velocity, while PIC keeps getting new velocity from grid every substep, but i am unsure of how to fix it.
