I am a new user for DualSPHysics and I was just experimenting with some cases. I faced some issues that I was hoping that you could help me with:
- I was trying to simulate a free-slip boundary condition and since I could not find any way on the forum or the documentation to do so, I thought that reducing the friction coefficient at the boundary to zero should also, logically, do the trick. Would that be a fair assumption to make?
- As a test case, I built a rotating cylinder and filled that with fluid. In the default condition, that was working just as expected. But then, I set the Kfric value of the material at the boundary to zero, and the results were still exactly the same, even though I had expected that there would not be any major movement of the enclosed fluid.
I am very confused with regards to the same. Am I interpreting the meaning of Kfric wrong? And if that is the case, is there any alternate method to simulate a free-slip boundary condition?
Any guidance would be greatly appreciated.
