Problem in particle trajectories calculation!!!

zahrae · October 8, 2019, 19:17

Hello!
I m simulating particles deposition by DPM model, when I enable the stochastic tracking I have many trajectories reported as incomplete!
I changed the maximum time step size to the maximum value (10^9) but the problem still remains, I have also changed the scheme in numerics from trapezoidal to Runge-Kutta the number of incomplete particles was reduced but It still even so.
Is the problem can be due to the considered mesh?
please any guidelines??
Thank you in advance!
