Background: there is a function I'm interested in reusing which takes the form

 tmp<volScalarField> foo(const volScalarField& arg);

...where the implementation sets each entry in the result based on the corresponding entry in arg only. I would like to apply this same operation to a single value but don't want to re-code foo. If I could create a fake internal mesh with exactly one entry, then I could pass this mesh to the volScalarField constructor and create a volScalarField with exactly one entry, which I could pass too foo. I could then extract the result I'm interested in from the single-valued result.

Is this possible? Is there another workaround?

Hello,

I really do not get the point you want to do? Why you want to build a volScalarField with a single entry. Do it with a dimensionedScalar or just a scalar. Provide more information and you will see that we can help you. With the lack of information, it is not really understandable; especially for people who are not sitting in front of your computer and are not related to the things you do.

hello knuckles,

I totaly agree with Tobi, I have no clue what you want. But what I think is that you need to take a look at C++ templates, widely used in OpenFoam. This gives you the possibility to use the same function with different kind of arguments

Hope this helps,
Wouter
