Hi Ehsan,

Unfortunately OpenFOAM doesn't have the calculation of entropy implemented for the "hConstThermo":
If you run this command:
ls -l $FOAM_SRC/thermophysicalModels/specie/thermoYou should...

OpenFOAM hasn't implemented all possible combinations of thermodynamic options.
You have to first check the list of valid combinations, as implied here:...

The problem is that the T field is not properly defined for the time instance "0". It's assuming values of 0 K (zero Kelvin!) for the "left" and "right" patches, which therefore leads to some massive...

OpenFOAM 2.2.0 has some broken stuff that has been already been fixed in 2.2.x....

Anyway, the quick fix is as follows:

Let's see...
So, it's calculated from the molar entropy, divided by the molecular weight.

The molar entropy is calculated depending on the equation of state. For example, in "janaf" it's...

"S" probably is used internally, but doesn't seem to be used for external consumption, such as generating the complete "S" field.


:confused: I don't understand the question... do you mean:

Hi Ehsan,

I think you can consider yourself very lucky today! I've managed to figure out a solution without having to hack directly into OpenFOAM's source code!
It took some C++ voodoo (mostly...

Hi Ehsan,

I didn't test it myself before... and I was assuming that if there was a "Cp", there should be an "S" as well... but apparently it doesn't exist yet! Looks like the OpenFOAM authors...

Hi Ehsan,

According to the paper you've indicated, it seems that the solver "rhoCentralFoam" was used to calculate entropy.

I've searched OpenFOAM's source code with the following command:...
