creating an internal field?

maybee · February 17, 2014, 16:10

hi,

as far as I have read here

http://www.cfd-online.com/Forums/ope...daryfield.html

a geometricField consists of an internal and a boundary field where values are stored in the center of each cell (internal field) and at the surface centers of each cell (boundary field).

My question is now can I create a field that only consists of the internal field or do I always have to create a full geometricField and access the internal field with e.g.

Code:

volscalarField MyField(...);
MyField.internalField() = ... ;

?

Reason I am asking this is, that I have to create many fields that only need/should have values in the center of each cell representive for the cell. Therefore I thought it would be unpractical to load them with a boundary field that won t be used.

greetings
