CFD Online Discussion Forums - [momentumPredictor] Frozen velocity field

Hello everyone,

Can someone tell me how to turn off the equations for the momentum for "foamMultiRun"?

I calculated the pre-initiated field of velocities and pressures. Now I want to calculate my case with only heat transfer. I turned off the flow equations in fvSolution. When I start running the case, the velocity are not calculated in residuals, but the velocity field still changes.

Please someone tell me what could be the problem?

fvSolution:

Code:

PIMPLE

{

    flow off;

    momentumPredictor off;

    nOuterCorrectors 30;

    nCorrectors     1;

    nNonOrthogonalCorrectors 0; 

...

    equationOfState rPolynomial;

    specie          specie;
