For some very fine mesh proble
 

For some very fine mesh problems I need to increase the maximum iteration limit from 1001 to say, 1500.

Can someone tell me where I can find this 1001 iteration limit so that I can change it to suit my needs. Specifically which source or header file?

Thanks!

Hi Srinath, Try here: Open
 

Hi Srinath,
Try here:

OpenFOAM/lnInclude/lduMatrixSolver.C: maxIter_(1000)

I hope is helpful,

Hi Dragos, Srinath, The max
 

Hi Dragos, Srinath,

The maxIter value in the source should be overwritten with the one read from the fvSolution file, as far as I am aware. These must be specified in OF-1.4.1 (at least I've had a lot of errors when they weren't). This goes for minIter too.
No recompilation needed.

Cheers
Andrew

The solvers section from fvSol
 

The solvers section from fvSolution in the cavity case of OF 1.4.1 contains the following:

solvers
{
p PCG
{
preconditioner DIC;
tolerance 1e-06;
relTol 0;
};

U PBiCG
{
preconditioner DILU;
tolerance 1e-05;
relTol 0;
};
}

Where is the maxiterations to be specified and what is the keyword and format?

Hi Srinath, just add maxI
 

Hi Srinath,

just add
maxIter 1000;
minIter 0;
after the relTol line in both solvers, (before the };)

Of course, change 1000 to be whatever new maximum you would like.

Cheers
Andrew

Thanks Andrew!
