Ivor,
I defined new boundary conditions for eTot which was a little tricky. A more elegant way is shown in rhoCentralFoam:


e = rhoE/rho - 0.5*magSqr(U);

Dear FOAMers,
I was wondering why the compressible solvers in OF solve a transport equation for static energy (or enthalpy)?

My idea was to keep the internal energy e but solve for the total...
