Dear all, I think we need to do a small discussion about concepts. For a numerical modeler what exits is the position of sea surface that is compute using a 2D mass balance equation where from the divergence of the barotropic flow you compute the time derivative of the sea surface. The oceanographer...

This is an interesting question. The inverse barometer by it self is not a forcing mechanism (water is approximately incompressible). Mohid is prepared to be forced by the term (-dpatm/dx, -dpatm/dy). MOHID can be forced with the gradients of atmospheric pressure. The options you connect was to acti...

The Hydrodynamic model of Mohid very robust but when there is a problem this is the typical error. Look at the courant number that the model sends as message to screen this value should be lower than 8 specially in enclose areas with channels. In open ocean can be a little bit bigger. Look at the ba...

As a general rule is always a good ideia do put far way the open boundary. If you are using clamped boundary conditions (imposed sea surface level) you might have problems in the cells where the open bounrady intersects land. Try to put you open boundary where depths are big and velocities are low. ...
