add temperature
 

HI!

I do the tutorial how to add temperature, but I want to add concentration, and the changes I made is to put C instead of T... with the same formula
I dont understand why the program gives me an error:

Does anyone knows why appears this error?

first "wclean" to clean previous .dep file
then use wmake

the same error appears...

Could you copy-paste the 7th line of CEqn.H? (that's where the error is, CEqn.H:7)

{
fvScalarMatrix CEqn
(
fvm::ddt(C)
+ fvm::div(phi, C)
- fvm::laplacian(DC, C)
);

CEqn.solve();

}

the 7th line is );

Could you try again without the { } ?
I think these make the concentration (C) a temporary object (tmp) and as a result you can not use any of the constructors.
And even if you could, it would be deleted from memory after the }.

you should define C as volScalarField, it seems you define it as scalar
