- The arc will frequently enclose an angle less than 180 degrees. For the case, it is possible to define the arc by its endpoints and its centre (origin) point. For example, arc 0 1 origin (0 0 0); When defined in the way, any discrepancy in the arc radius for the endpoints is resolved by adjusting the origin to ensure that the average radius is satisfied. It is also possible to specify a \em flatness factor as a multiplier of the radius. For example, arc 0 1 origin 1.1 (0 0 0); ENH: minor code cleanup for block edges ENH: expose point appending as polyList::concat

- avoid potential ambiguities in naming of mesh faces/edges vs. block faces/edges - additional methods characterizing the number of faces (internal, boundary, total) associated with a blockDescriptor - cellLabel() accessor and checkIndex() methods - restore demand-driven behaviour of block, cache the calculated cells and refactor generation of block boundary faces to improve potential reuse.

New functionality contributed by Mattijs Janssens: - new edge projection: projectCurve for use with new geometry 'searchableCurve' - new tutorial 'pipe' - naming of vertices and blocks (see pipe tutorial). Including back substitution for error messages.

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); radius 1; } } 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.

- the blockMesh interface is splineEdge.H, selectable as "spline" The first tests look fine - it works as expected for the case with buggy polySpline reported on the forum. Should of course do some more extensive testing. The advantages compared to the current B-Spline implementation: - Doesn't need a matrix solver. - The coding resembles something that can be found in the literature. - In contrast to the B-Spline implementation, it is fairly clear what is actually going on. I don't even know if the B-Spline are actually B-Spline, Beta-Splines or something else. - Catmull-Rom splines seem to be what all the graphics people have as their stable workhorse. We now have 3 different names for splines in blockMesh: - "spline" - *new* Catmull-Rom for arbitrary segments. - "simpleSpline" - B-Spline for a single segment - "polySpline" - B-Spline for a multiple segments Assuming the Catmull-Rom splines continue to behave nicely, there is no reason to keep the other (broken) B-Splines. This would help clean up the blockMesh interface too. Placed the older ones under legacy/ for easier identification in the future. TODO: - currently no handling of non-zero end tangents - could be extended to handle closed loops, which might be useful for feature edges from CAD (eg, for the cvm mesher)

- slightly better code isolation, dropped unneed variables, changed vector -> point in the appropriate places - the spline stuff is still horribly broken. Needs a complete rewrite or needs to get chucked.

- also sifted through code to find out why polySplineEdge is going wrong It doesn't seem to be a virtual/non-virtual issue, but appears to be an issue with how BSpline is solving for the new points.

- Unless the points(), cells(), patches() methods are called, the classes should know maintain a lightweight representation for as long as possible. - bugfix: old-code used xferMove() instead of xferCopy() when creating the topology mesh - causing const pointField& to break if the code order was changed - relocate blockMesh from src/meshing -> src/mesh
