Solid boundaries are treated as fluids
Hi，guys. I'm a novice in dualsphysics.
When I constructed an open channel flow with obstacles by referring to the example of "examples\inletoutlet\02_OpenChannel", I found that my solid boundary seemed to move.It is contained in the “PartFluid0.vtk” file. The following is my XML file and the problems.
As shown in the figure, the fluid and boundary are separated before the movement, but after the movement, the boundary is included in the fluid part.
After I remove the obstacles, the same problem will still occur.
Then, I tried to add a box in "examples \ inletoutlet \ 02_openchannel", and no exception occurred.
I have tried to modify dp, and also tried to increase the distance between the boundary and the fluid particles. But they have not solved this problem.Instead, sometimes the fluid particles at the outlet buffer will penetrate the boundary.
How can I solve this problem？
