Klingbeil et al. (2014) proposed a theory of estimating numerically induced mixing coefficients. At the moment we have only implemented this module for 1 tracer (salinity).
The I.C. for this module is hardwired to be 0 and the code will set it automatically. The B.C. flags should also be 0 in general, so is the nudging flag. The main output is iof_dvd(1)
which corresponds to numerical mixing for salinity in \(\text{PSU}^2/s\).
