Hi,

I have a 3D model that has been validated with salt and currents. Recently, I started using the viscosity for tracers in the vertical axis (NAZ) and I noticed that I'm getting huge negative values in some regions and smaller positive values in other regions of the model. Is this normal? What can I do to work with these values? Ignore the negative? Ignore the positive?
Should I run the model again?

I'm using
VERTICAL TURBULENCE MODEL = 3
HORIZONTAL TURBULENCE MODEL = 3

Thanks in advance,
Cristian
