Hi all,
I want to simulate a system contain two phase water and air which constitute from SPH particles. To define interaction between two phase, I have used two methods (at below). But in all of them, those particles of air or water which come close to interface, either disappear suddenly or interpenetrate inside each other.
method 1:
pair_coeff 1 3 sph/idealgas 1 0.045
pair_coeff 1 3 sph/rhosum 0.045
method 2:
pair_coeff 1 3 sph/lj 1 0.045
how can i define this interaction correctly?
Thanks
