Hi,

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

Code:

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:

Code:

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":

Code:

Valid functions are :
