FrazilInit._compute_temperature_salinity(config, ds, x_cell)

Compute the melting or freezing initial temperature and salinity profiles. Salinity increases linearly with depth in both cases. In the melting case, temperature is a constant value above a transition depth and a different constant value below it. In the freezing case, temperature is uniform, just above the warmest linear freezing point for MPAS-Ocean or set by temperature_freezing for Omega. It is exactly at the local freezing point if at_freezing is set. In the melting_short case, temperature is constant above the transition depth and a fixed amount below the local freezing point beneath it.
