Syntax question relating volScalarField
 

Hi Foamers,
I have the following question is it possible to "force" a volScalarField in this way?

volScalarField somethingSomething
(
IOobject
(
"somethingSomething",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
mesh,
dimensionedScalar("zero",dimensionSet(1,0-1,0,0,0,0),A*B)
);
with the product of A*B having a different dimension, i.e. to overwrite the dimension?

So basically this

If A and B are dimensionedScalars

if they form a volScalarField, you just remove mesh, like this

I found the best thing to do is define another dimensionedScalar with value 1.0 (call it, say, dimensionConversionAB) that has the dimensions required to convert from the dimensions of A*B to the dimensions you require. That way you don't forget that you're doing something a bit dodgy when you come to look back at your code.

dimensionSet(1,0,-1,0,0,0,0) is the correct.... a "," was misssing
