discussion "saturation dependend thermal conductivity"
There are two different MPL properties that implement two different saturation dependent thermal conductivity laws: SaturationDependentThermalConductivity and SoilThermalConductivitySomerton. In theory, it is also possible now to use the Function property instead. However, I think it is a quite often used feature, so it makes sense to have at least one MPL property. Whereas the first law is implemented only for scalar conductivities, the Somerton law is implemented for tensorial conductivities as well. What I would like to discuss is whether we should have
- individual properties for individual laws (but with a unified naming)
- one saturation dependend property that implements different laws accessible by additional attributes
- no property as all laws are simple and the Function type can be used instead
