Performs the boundary effect on the fluid particles.

Parameters
isetSet of particles index.
imoveMoving flags.
  • imove > 0 for regular fluid particles.
  • imove = 0 for sensors.
  • imove < 0 for boundary elements/particles.
imirrored0 if the particle has not been mirrored, 1 otherwise.
rPosition \( \mathbf{r} \).
rmirroredMirrored position of the particle, r if imirrored is false (0).
normalNormal \( \mathbf{n} \).
nmirroredMirrored normal of the particle, normal if imirrored is false (0).
uVelocity \( \mathbf{u} \).
umirroredMirrored velocity of the particle, u if imirrored is false (0).
rhoDensity \( \rho \).
pPressure \( p \).
massMass \( m \).
refdDensity of reference \( \rho_0 \) (one per set of particles)
grad_pPressure gradient \( \nabla p \).
div_uVelocity divergence \( \nabla \cdot \mathbf{u} \).
icellCell where each particle is located.
ihocHead of chain for each cell (first particle found).
NNumber of particles.
n_cellsNumber of cells in each direction
gGravity acceleration \( \mathbf{g} \).
