solver settings for reactingFoamAnother newbie's question, if I may impose on the forum users.
I am running reactingFoam on OpenFoam 1.5. The reactingFoam I downloaded was developed in v1.4 and the system keeps conplaining the input found in fvSolution. I did the following to get it to work but am quite clueless if what I did was even close to being right. Any suggestions/comments will be grealy appreciated. The original settings solvers choice and setting are: solvers { rho ICCG 1e-06 0; U BICCG 1e-06 0; p ICCG 1e-09 0; Yi BICCG 1e-06 0; h BICCG 1e-06 0; k BICCG 1e-06 0; epsilon BICCG 1e-06 0; } and the one I put in to get it to work with v1.5 are: solvers { rho ICCG { preconditioner DILU; tolerance 1e-06; relTol 0; }; U PBiCG { preconditioner DILU; tolerance 1e-06; relTol 0; }; p PCG { preconditioner DIC; tolerance 1e-06; relTol 0; }; Yi PBiCG { preconditioner DILU; tolerance 1e-06; relTol 0; }; h PBiCG { preconditioner DILU; tolerance 1e-06; relTol 0; }; k PBiCG { preconditioner DILU; tolerance 1e-06; relTol 0; }; epsilon PBiCG { preconditioner DILU; tolerance 1e-06; relTol 0; }; |

Jerry,
Looks equivalent to me, unless I am missing something. Note that for rho in reacting foam, the fvSolution settings don't really matter, since you get a diagonal system from rhoEqn.H: { solve(fvm::ddt(rho) + fvc::div(phi)); } -David |
