When I run the FLOW model without any boundary conditions (just a steady wind comprised of a uniform x-field and y-field) the resulting flow runs parallel to the edge of the grid, following the edges round in a loop (like the boundary is solid). What boundary conditions need imposing to prevent this effect?<br /><br />Thanks in advance for any help.Harvey Cairns2022-12-05T12:57:09Z
