See if we can get a better solution by adding \vec{v}\cdot\nabla p
in the energy balance somehow
For incompressible fluids we have at least two options:
- Assemble internal energy fluxes instead of enthalpy fluxes, the volume work term disappears (not generic)
- Add the missing term and keep assembling enthalpy fluxes
There might be other solution by inserting the continuity equation to turn the term into some time derivative.
