I am working on a custom fvOption that is writing a field at normal outputTimes using

if (mesh_.time().outputTime())
{
    myField.write();
}

However, the field is not written when the steady state solver (simpleFoam) converges--the most important time to write! What other condition can I use to make this field write?

Hi Pete,

If you have residualControls defined in the fvSolution file, simpleFoam should write and stop as soon as all of the criteria are satisfied. Is this different than what you are trying to do with the function object?

Cheers!

Kyle,

This is indeed what I'm trying to do. What I gather is the final time is not an outputTime, so my field is not writing, but all the other OpenFOAM fields write.

Right.

The issue is likely this: The convergence check is performed within the simple.loop() call at the beginning of the simple loop. If its satisfied, then it writes and stops.

If you look at ::loop()

/src/finiteVolume/lnInclude/simpleControls.C

You'll see that it will drop out before returning time.loop() later in the function. <- this is what was about to call your function object but it stopped before hand.
