how to calculate the pressure in gimp method

[commatrixs]

hi,

Thanks for your code. I read the code with the dam break example. I have realized the pressure for weakly compressible fulid is calculated in the cell center when standard mpm is employed. I want to use gimp which has a bigger domain. In this case, I would like to know the pressure calculation method. Is the pressure of particle equal to the center pressure of cell which particle location located in? Or is it necessary to perform a weighting operation to average the pressure of cells within the particle influence area?

Best regards
