Bottom friction
Hi, I have some doubts when setting the bottom stress parameters in croco.in. If you run in 3D (SOLVE3D) and choose a logarothmic bottom friction (zob in croco.in) the modell computes 3d velocities using that friction parameters (in get_vbc.F), thatś fine, but in the barotropic model (2d), the model uses a linear or cuadratic function (in STEP2D.F) to calculate ubar/vbar, so in the end the model may be using different friction parameters in de 2d and 3d cases, is this ok??. Is there a way to define manually the fricton parameters for the barotropic model?, i read something you can do in roms defining the cuadratic parameter rdrg2(i,j) in the grid file but not in croco... I need to put more friction in some places where the tide currents are too big and the simulation ends blowing up (my dt is very small yet, i dont want to lower it more). Thanks, Nicolas
