Hello,


I'm trying to write out the enthalpy at each timestep.
since I chose sensible enthalpy in the thermophysicalProperties file "he" that is used for the energy equation should be the enthalpy.

I tried adding


Code:
volScalarField he 
     ( 
         IOobject 
         ( 
             "he", 
             runTime.timeName(), 
             mesh, 
             IOobject::MUST_READ, 
             IOobject::AUTO_WRITE 
         ), 
         thermo.he() 
     );
to the createFields.H file and recompiling.


But the "he" that is written out is not changing from one timestep to the next although it should.


Does anyone know what I'm doing wrong and can point me in the right direction?



Thanks,


Caro

Just define sensibleEnthalpy in thremophysicalProperties and use:

thermo.he().write();
