unknown asymmetric matrix solver
 

Hello,

I am trying to use the BiCGStab method, but it doesn't appear to be available. I'm running 1.6-ext, and using my own multiphase solver. In my case, the following methods appear to be available,

Valid asymmetric matrix solvers are :

(
GAMG
smoothSolver
PBiCG
BICCG
)

The strange thing is, I am able to use BiCGStab in the cavity and damBreak tutorial cases. In cavity, I have the following solvers to choose from,

)

Can anyone help me understand why I can use BiCGStab with icoFoam in the cavity case, and cannot use it with my own solver in my own case?

Thanks for your help!

I would check your Make/options file to see if the same libraries are loaded as icoFoam. If the entries are missing, then the appropriate libraries have not been linked to your solver.

Also, how different is your solver to icoFoam?

That was it, I wasn't linking to the lduSolvers library. Adding -llduSolvers to Make/options got me going. Thanks!
