[MITgcm-support] FW: Diagnose momentum equation

[lianzhan]

Hello everyone

I want to diagnose the effect of all items in momentum equation (as below for zonal).
dU/dt+UdU/dx+VdU/dy+WdU/dz=fv-1/rho*dP/dx+Fx+taux/rho
Fx is dissipative stress, taux is wind stress. Is there any corresponding variable in pkg/diagnostics ? I have tried "U/Vm_Advec" for nonlinear term, but this variable is zero expect for the surface layer. Its value is as same as "U/Vm_Cori", the value of "U/Vm_Cori" is also zero below surface. And "U/Vm_dPHdx"(pressure gradient force ? ) is all zero.
The settings of my exp is that there is an island located in an ideal rectangular bay,  near which there is a sill. The model has 32 vertical layers and with free surface. The Temp/Salt is uniform. 
Do you have any recommendations or suggestions?
Thanks in advance for your helpCheers,Lianzhan
