Setting volume fraction in a specific block?

tbolt427 · February 28, 2011, 18:50

Hi All

I have a basic question that I can't seem to figure out in the docs. I have a domain consisting of two blocks. For the interFoam examples, setFieldsDict always uses boxToCell to set non-default values for alpha1. That is,

regions
(
boxToCell
{
box (0 0 -1) (0.1461 0.292 1);
fieldValues
(
volScalarFieldValue alpha1 1
);
}
);

Is there a method to set alpha1 in a block that has been defined in blockMeshDict?

Thanks

Thanks for the reply. I'll look at the wiki.

I thought about writing code to setup 0/alpha1 but it doesn't seem that it is simple to figure out which cells belong to a given block.

Again, thanks for the tip.
