Inlet/outlet 2d : Domain size of particles in direction X is not zero.
I am a new user of DualSPHysics, trying to build a 2d case with inflow boundary conditions using Freecad.
The case with closed boundaries works well, but I have an error when trying to use an open inflow boundary (small blue rectangle on the left in the picture below):
The error returned is: Domain size of particles in direction X is not zero.
My geometry is completely defined in the x-z space (i.e. y=0 everywhere). I see in the OpenChannel example that there is a thickness in the y-direction despite that it is a 2d case.
Any hint on how to debug this error?
