Hi,

I would like to evaluate run-time the total kinetic energy through a function object:

kineticEnergy
{
    type expressionField;
    outputControl timeStep;
    outputInterval 1;
    fieldName kineticEnergy;
    expression "U&U+k";
    autowrite true;
}

At the beginning of controlDict I've added the following libs:

libs 
(
    "libmyIncompressibleRASModels.so" 
    "libsimpleFunctionObjects.so" 
    "libsimpleSwakFunctionObjects.so" 
    "libOpenFOAM.so" 
    "libgroovyBC.so"
);

OF complains that expressionField is not a valid entry. I've correctly compiled swakFoam, in fact I can use all its other entries.

Here the result of the "banana test":

Valid functions are : 

54
(
correctThermo
dumpSwakExpression
dumpSwakGlobalVariable
dynamicFunctionObjectListProxy
executeIfEnvironmentVariable
executeIfExecutableFits
executeIfFunctionObjectPresent

)

Can someone help?

Thanks in advance.

Hi,

I've found the mistake. I didn't add the libswakFunctionObjects.so to libs.
