VolScalarField without boundary conditions

kar · February 24, 2008, 15:02

Hi,

I tried to figure out how to create some volScalarField, that has no boundary conditions, but looks like GeometricField is supposed to always have them. Setting "empty" BCs makes an error.
Is it possible to create such field? If yes, have you found it useful?
Not sure if that's really necessary, but I'm curious..

Hi Karlis,
I created a solver and cases for a variable thermal conductivity and thermal capacity. The rhoCp field had zeroGradient on all sides and empty on the Front and Back planes. The internal field is specified as either uniform or non-uniform. I don't know if that's exactly what you were looking for, but it might be similar.

Regards,
Mike J.

Make a DimensionedField<scalar,> instead.
