WIP: [material][constant] Put volume work energy into storage term / internal energy
Harmonize enthalpy/internal energy of
Constant component with the
This is how it's done in
@holle Can you comment on this? Numerically it seems to make a difference if the consitutive law, i.e.
dh = du + pdv is inserted for
u or for
h. It seems to me easier to account for the volume work in the volume integral.
Constant component seems to be correct and
SimpleH2O is the one that has a bug (wrong enthalpy and thus internal energy). So we shouldn't merge this but fix
