Hi,

I have been struggling to set the alpha.water field using boxToCell. I have tried to follow the suggestons in Trying to understand: What is the "boxToCell"? as well as the dambreak tutorial. However I have not succeeded after several attempts.

My blockMeshDict is as follows :

{

format ascii;
class dictionary;
object blockMeshDict;
}

);

and the setFieldsDict is as follows :

FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "system";
object setFieldsDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

defaultFieldValues
(
volScalarFieldValue alpha.water 0
);

regions
(
boxToCell
{
box (-1 -1 -1) (6 1 0.5);

fieldValues
(
volScalarFieldValue alpha.water 1
);
}
);


would it be possible to make suggestions as to select the rectangular prism to set the water field ?
