I’m facing unexpected edge-effects in a super simple 2D-Liquid-Flow simulation.
As you can see from the case attached, the 2D domain is 10 x 10 cm, 1mm structured grid, source term on the left edge, boundary condition on the right edge. The case should be very similar to the “H/sat_1D” benchmark and thus I expected a straight distribution from “some” pressure on the left to 0 Pa on the right side, but as you can see in the plot, the pressure distribution on the left side is not straight and on the right side the pressure drops to (almost) 0 about 0.9cm = 9 cells away from the boundary. Any ideas? OGS-Version 5.5.4
In case I get that running, I would like to model a heterogeneous sediment similar to the “H/HetGWFlow/2D” example. In this example, a permeability list is used. Is there a way to map these kind of lists from an ascii/excel/whatever file for more complicated geometries and unstructured meshes?
Finally, Is there a way to map boundary conditions from a file to a polyline or surface? If not, I guess “DIRECT” would work for me as well.
