Have any one been able to simulate the closure of a tank without experiencing this phenomena?
This happens a few time steps after the tank has been fully closed, suddenly particles "explode" and get very disorganized.
The white box has a prescribed velocity in the x direction, which closes the opening off. Any suggestions for some settings to tune?
Currently I am using symplectic scheme, Wendland kernel, LES-SPS and double precision. Hoping to hear some of your experiences.
