I would like to simulate 2D unsteady channel flow for arbitrary geometry.
I guess that it is suitable to do such simulation by using the Moving Time Window Method as like Taylor Green Vortex Decay (section 6 in the simnet user guide).
To do this, I should modify “def make_periodic_boundary…” in the Solver domain in taylor_green.py.
However, I have no idea which boundary condition should be written in the Solver domain.
Is it OK to write geo.boundary_bc(…) in the Solver domain as like the Train domain in the ldc_2d.py?
