An Efficient Sleepy Algorithm for Particle-Based Fluids

Algorithm 2

Sleepy SPH/WCSPH algorithm.

while simulating do

 determine different particle types

 for intermediate particles do

  neighbor search

 for non-sleepy & intermediate particles do

  density computation according to (2)

  pressure computation according to (3)

 for non-sleepy particles do

  if pressure is non-negative

    pressure force computation according to (4)

  else

    repulsive force computation according to (7)

  viscosity force computation according to (5)

  other forces computation

 for non-sleepy particles do

  time integration
