[swak4Foam] swakFunctionObject

rapierrz · February 12, 2015, 02:34

Hi friends.
I have a problem with swakFunctionObject for nusselt calculation.
my openfoam version is 2.2.1 .
libs (
"libOpenFOAM.so"
"libsimpleSwakFunctionObjects.so"
"libswakFunctionObjects.so"
);

functions
(
NusseltNumber
{
type patchExpression;
patches (
down
);
verbose true;
variables (
"Tsat=500;"
"lc2D=0.0072301;
);
expression "lc2D*snGrad(T)/(T-Tsat)";
accumulations (
max
min
average
);
}

);
and error is : unknown function type patchExpression

thank you.

Hello,

Try to add this library to your controlDict

Code:

    "libsimpleFunctionObjects.so"

I am using this function object right now without a problem and I have your libraries plus the one I said above added to my controlDict file.

Regards,

Alex
