Class
    Foam::functionObjects::multiply
 
Description
    Multiply a list of fields.
 
    The operation can be applied to any volume or surface fields provided that
    the resulting multiplication does not produce a tensor of rank greater than
    two.
 
    Example of function object specification:
    \verbatim
    Ttot
    {
        type            multiply;
        libs            ("libfieldFunctionObjects.so");
        fields          (rho U);
        result          rhoU;
        executeControl  writeTime;
        writeControl    writeTime;
    }
    \endverbatim
