Algorithm 1

Coupled grid-particle method for the free surface.

Update physical information of particles based on SPH

Update physical information of grids based on improved LBM-VOF

for all grid interface grids do

 if grid abnormal grids then

   Generate particle at position by using Eq.(14)

   Calculate physical information for the particle by using Eq.(15) - Eq.(17)

   Delete the abnormal grid

  end if

for all particle SPH do

 Calculate the grid position of the particle by using Eq.(19)

 if interface grid positions then

  Calculate physical information for the grid by using Eq.(21) - Eq.(23)

  Recalculate DF of the grid by using Eq.(1)

  Delete the particle
