Dictionary entries constructed with #calc and #codeStream can now
conveniently access and use typed variables. This means calculations
involving vectors and tensors and list and field types are now possible.
To access a variable and construct it as a given type within a #calc
or #codeStream entry, put the type immediately after the $ symbol inside
angled brackets <>. So, $<vector>var or $<vector>{var} substitutes a
variable named var as a vector.
Examples:
- Reflect a point in a plane defined by a normal
p (1 2 3);
n (1 1 0);
pStar #calc "$<vector>p - (2*sqr($<vector>n)/magSqr($<vector>n)&$<vector>p)";
- Rotate a list of points around an axis by a given angle
points ((3 0 0) (2 1 1) (1 2 2) (0 3 3));
rotation
{
axis (0 1 1);
angle 45;
}
#codeStream
{
codeInclude
#{
#include "pointField.H"
#include "transform.H"
#};
code
#{
const pointField points($<List<point>>points);
const vector axis = $<vector>!rotation/axis;
const scalar angle = degToRad($!rotation/angle);
os << "pointsRotated" << nl << (Ra(axis, angle) & points)() << ";";
#};
};
- Compute the centre and trianglation of a polygon
polygon ((0 0 0) (1 0 0) (2 1 0) (0 2 0) (-1 1 0));
#codeStream
{
codeInclude
#{
#include "polygonTriangulate.H"
#};
code
#{
const List<point> polygon($<List<point>>polygon);
writeEntry(os, "polygonCentre", face::centre(polygon));
polygonTriangulate triEngine;
triEngine.triangulate(polygon);
os << "polygonTris" << ' ' << triEngine.triPoints() << ";";
#};
};
- Generate a single block blockMeshDict for use with snappyHexMesh with no redundant information
min (-2.5 -1.2 -3.0); // Minimum coordinates of the block
max (2.5 1.2 3.0); // Maximum coordinates of the block
nCellsByL 33.3333; // Number of cells per unit length
// Calculate the number of cells in each block direction
nCells #calc "Vector<label>($nCellsByL*($<vector>max - $<vector>min) + vector::one/2)";
// Generate the vertices using a boundBox
vertices #codeStream
{
codeInclude
#{
#include "boundBox.H"
#};
code
#{
os << boundBox($<vector>min, $<vector>max).points();
#};
