Adding temperature to icoFoam

[aesovoy]

Hello, I was following a tutorial (link below) for adding temperature to icoFoam. The solver was compiled correctly, but then when I run it on an example case (a modified cavity case), I get the following message:

--> FOAM FATAL IO ERROR:
Unknown asymmetric matrix solver BICCG
Valid asymmetric matrix solvers are :
3
(
GAMG
PBiCG
smoothSolver
)

I'm doing exactly what the tutorial says, but due to the different versions of openFoam I guess, the procedure is not the same. How can I incorporate the BICCG solver in the modified version of icoFoam? I would appreciate if I could get any orientation on this.

I've re-opened this issue because I was asked about the compatibility of this tutorial with OpenFOAM 4 the other day as well. We'll have to fork the wiki page for adding support for OpenFOAM 4 and possibly 3.0 as well.

To answer your question, it should just be as simple as using PBiCG instead of BICCG.

Additional notes of what I wrote to whom asked me about this:

This:

    DT            DT [0 2 -1 0 0 0 0] 0.002;

Changed to something like this:

    DT            [0 2 -1 0 0 0 0] 0.002;

Still on chapter 5, the first command changed from this:

cd $FOAM_RUN/tutorials/incompressible/icoFoam

to this:

cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity

Because the cavity cases now have their own folders.

Thanks for the answer! That's what I finally made, changed the solver from BICCG to PBiCG and worked perfect.
