The rotatedBoxToCell topoSet source can now be specified by providing
the geometry of a non-rotated box and how it should be rotated. For
example, in system/topoSetDict:
actions
(
{
name c1;
type cellSet;
action new;
source rotatedBoxToCell;
box (0.4 0.4 -100) (0.6 0.6 100);
centre (0.4 0.4 0);
n1 (1 0 0);
n2 (1 1 0);
}
);
This selects cells in a box rotated from (1 0 0) to (1 1 0) (i.e., 45
degrees around the z-axis), with width and depth of 0.2, height of 200,
and with a bottom left corner at (0.4 0.4 -100).
The origin, i, j, k, specification is still available, and will be used
if the keyword "box" is not present. The equivalent input to the above
in this form is as follows:
actions
(
{
name c1;
type cellSet;
action new;
source rotatedBoxToCell;
origin (0.4 0.4 -100);
i (0.141421 0.141421 0);
j (-0.141421 0.141421 0);
k (0 0 200);
}
);

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
