• blockMesh: New experimental support for projecting block face point to geometric surfaces · 00920318
Henry Weller authored
For example, to mesh a sphere with a single block the geometry is defined in the
blockMeshDict as a searchableSurface:

geometry
{
sphere
{
type searchableSphere;
centre (0 0 0);
}
}

The vertices, block topology and curved edges are defined in the usual
way, for example

v 0.5773502;
mv -0.5773502;

a 0.7071067;
ma -0.7071067;

vertices
(
(\$mv \$mv \$mv)
( \$v \$mv \$mv)
( \$v  \$v \$mv)
(\$mv  \$v \$mv)
(\$mv \$mv  \$v)
( \$v \$mv  \$v)
( \$v  \$v  \$v)
(\$mv  \$v  \$v)
);

blocks
(
hex (0 1 2 3 4 5 6 7) (10 10 10) simpleGrading (1 1 1)
);

edges
(
arc 0 1 (0 \$ma \$ma)
arc 2 3 (0 \$a \$ma)
arc 6 7 (0 \$a \$a)
arc 4 5 (0 \$ma \$a)

arc 0 3 (\$ma 0 \$ma)
arc 1 2 (\$a 0 \$ma)
arc 5 6 (\$a 0 \$a)
arc 4 7 (\$ma 0 \$a)

arc 0 4 (\$ma \$ma 0)
arc 1 5 (\$a \$ma 0)
arc 2 6 (\$a \$a 0)
arc 3 7 (\$ma \$a 0)
);

which will produce a mesh in which the block edges conform to the sphere
but the faces of the block lie somewhere between the original cube and
the spherical surface which is a consequence of the edge-based
transfinite interpolation.

Now the projection of the block faces to the geometry specified above
can also be specified:

faces
(
project (0 4 7 3) sphere
project (2 6 5 1) sphere
project (1 5 4 0) sphere
project (3 7 6 2) sphere
project (0 3 2 1) sphere
project (4 5 6 7) sphere
);

which produces a mesh that actually conforms to the sphere.

See OpenFOAM-dev/tutorials/mesh/blockMesh/sphere

This functionality is experimental and will undergo further development
and generalization in the future to support more complex surfaces,
feature edge specification and extraction etc.  Please get involved if
you would like to see blockMesh become a more flexible block-structured
mesher.

-case <dir>       specify alternate case directory, default is the cwd
-dict <file>      specify alternative dictionary for the blockMesh description
-noFunctionObjects
do not execute functionObjects
-region <name>    specify alternative mesh region

-help             print the usage

Block description

For a given block, the correspondence between the ordering of
vertex labels and face labels is shown below.
For vertex numbering in the sequence 0 to 7 (block, centre):
faces 0 (f0) and 1 are left and right, respectively;
faces 2 and 3 are bottom and top;
and faces 4 and 5 are front the back:

4 ---- 5
f3   |\     |\   f5
|    | 7 ---- 6   \
|    0 |--- 1 |    \
|     \|     \|    f4
f2     3 ---- 2

f0 ----- f1
