Hello all,

I am using a Finite point method solver.
In the first case when i used an initial time step of 0.001 for a point distance of 1.25 mm my simulation did not produce any errors.
Now when i used an intial time step of 0.003 for a point distance of 3.75 mm i get a divergence error with respect to pressure. Can anyone help me this? I am performing a multiphase simulation with flow in a pipe.
