Density question: why rho becomes b

[kerim371]

Hi,

Can't understand the meaning of physical parameter b.
Especially if we look at the source code then we can see that b = 1f0 ./ rho in case when minimum(rho)/maximum(rho) > 0.1.
In my case minimum(rho) = 1.0f6 (g/m^3) and maximum(rho) = 2.5134072f6 (g/m^3).
As 1.0f6 / 2.5134072f6 > 0.1 thus rho becomes b.

In the comment to the commit I can see that this is done for Julia 1.8 and I'm using Julia 1.6.5

b is the buoyancy i.e inverse of density. Makes the compute easier to reparametrize with it
