About wall boundary of SPH
 
Hi

The ghost particles seem not suitable for complex geometry. But the expression of Lennard-Jones force has some parameters dependent on case. Is there some rigous way to determin the parameters?

I think, the ghost particles is rhe best case because the pressure valus is very smooth and the computational is cheaper
