liquid properties in OF 2.2.0
Hi all,
when I am using a lagrangian solver and inject a liquid it is not possible to use non default coefficients for the fluid properties in the thermophysicalProperties file.

Then I recieve the error message that Foam::scalar Foam::liquidProperties::pv(scalar, scalar) is not implemented.
Due to that error I compiled the liquid properties from OF 2.1.0 in OF 2.2.0.
Now it is possible to use non default coefficients.
Is there a bug in the liquidProperties.C file in OF 2.2.0?
Or is the way I give the non deafult coefficients wrong (it was the right way for OF 2.1.0)
Thanks your hints in advance!
Kind regards
