Dear Foamers,


I am encountering a problem using setExprBoundaryField with OF-2106. Indeed, it seems that it cannot read the condition specified in the dictionary below.


Can someone explain me the reason?
Thank you in advance,
Luca

updateBCs
{
    field   T;

    nonUniformHeatFlux
    {
        target  value;
        variables
        (
            "zMin = 5"
            "zMax = 10"
        );
        condition
        #{
            (pos().z() > zMin && pos().z() < zMax)
        #};
        expression
        #{
            pos().z()
        #};
    }

    expressions
    (
        { $nonUniformHeatFlux; patch walls; }
    );
}

EDIT:
I have realized that the conditional statement works if inside the expression, as listed in the code below:

updateBCs
{
    field   T;

    nonUniformHeatFlux
    {
        target  value;
        variables
        (
            "zMin = 5"
            "zMax = 10"
        );
//        condition
//        #{
//            (pos().z() > zMin && pos().z() < zMax)
//        #};
        expression
        #{
            (pos().z() > zMin && pos().z() < zMax) ? pos().z() : 0
        #};
    }

    expressions
    (
        { $nonUniformHeatFlux; patch walls; }
    );
}

Anyway, I find quite strange that the first code works with setExprFields and not with setExprBoundaryFields, as should be the case according to the manual page https://www.openfoam.com/news/main-n...pre-processing
