suggest that we use more clear name for the physical properties:

DENSITY ➔ MASS_DENSITY
Reflects that it’s the density related to mass in a fluid context.

VISCOSITY ➔ DYNAMIC_VISCOSITY
Highlights that it’s the fluid’s resistance to flow.

CONDUCTIVITY ➔ THERMAL_CONDUCTIVITY
Clarifies that it’s related to heat transfer rather than electrical conductivity.

THis has been a weakness in the current code also.

I have renamed, but not updated the tests. Should it still be possible to write initPhysicalProperties("viscosity") with the old short names?

Yes - It would be good to keep compatibility with old code, so maybe accept both viscosity and dynamic viscosity
