Particles moving upward in wave generation

mtmtmt

July 2022 in DualSPHysics v5.0

Dear all,

I faced some problems while attempting to run a 3D wave flume model in project chrono, the problem is that

particles start to move upward from SWL.

i tried different dp and h for my model. also (artificial and Laminar+SPP) and ( pressure correction method:molteni, Fourtakas,..)

i would be grateful if anyone could help me to solve the problem.

Dear @Myiced and @lormal
I use particle shifting and simulation work correctly.
Kind regards.

The simulation should work ok WIHTOU shifting, the issue should be sthg else
Can you share your XML?

Restart from scratch from a similar base case. You properly entered a wrong value for the diffusion coefficient.
Kind regards
