- renamed 'core/' -> 'base/' to avoid gitignore masking when re-adding
files
- rename 'nas/' to 'nastran/' for more clarity
- relocated OBJstream from surfMesh to fileFormats
STYLE: remove unused parseNASCoord. Was deprecated 2017-09
Issues:
- neighbouring processors use different ray since always from
owner cc to nbr cc
- growing cellZones did not correctly unmark intersections
- stand-alone baffles now always removed (if inside 'grow' region,
i.e. within 1 cell of cellZone)
This adds automatic deletion of cells inside small gaps. This is
generally used to avoid having excessive numbers of cells in irrelevant
areas of a geometry. It is nearly the opposite of automatic gap refinement
- that refines cells to resolve the gap; this functionality removes cells
to not mesh the gap.
The proximity handling will remove those cells which are inside 'thin' gaps
where 'thin' is defined as a distance of 2*'blockLevel'
It will
- detect surfaces which have the new 'blockLevel' specification
- convert this to a minimum gap distance
- detect cells which are inside this gap
- remove these cells and add exposed faces to the nearest 'real' patch
- change contiguous from a series of global functions to separate
templated traits classes:
- is_contiguous
- is_contiguous_label
- is_contiguous_scalar
The static constexpr 'value' and a constexpr conversion operator
allow use in template expressions. The change also makes it much
easier to define general traits and to inherit from them.
The is_contiguous_label and is_contiguous_scalar are special traits
for handling data of homogeneous components of the respective types.
- Eg, with surface writers now in surfMesh, there are fewer libraries
depending on conversion and sampling.
COMP: regularize linkage ordering and avoid some implicit linkage (#1238)
- construct from positions
- reset positions, minEdgeLen, find grid index
ENH: add accessor for obtaining the size of a single i-j-k dimension
- eg, obtain the 'i' dimension with any of these methods:
ijkAddr.size(vector::X)
ijkAddr.sizes().x()
ijkAddr.sizes()[0]
- While a rectilinear mesh can be created with blockMesh, not every mesh
created with blockMesh will satisfy the requirements for being a
rectilinear mesh.
This alternative to blockMesh uses a single block that is aligned
with the xy-z directions and specifications of the control points,
mesh divisions and expansion ratios. For example,
x
{
points ( -13.28 -0.10 6.0 19.19 );
nCells ( 10 12 10 );
ratios ( 0.2 1 5 );
}
y { ... }
z { ... }
With only one block, the boundary patch definition is simple and the
canonical face number is used directly. For example,
inlet
{
type patch;
faces ( 0 );
}
outlet
{
type patch;
faces ( 1 );
}
sides
{
type patch;
faces ( 2 3 );
}
...
- After a mesh is defined, it is trivial to retrieve mesh-related
information such as cell-volume, cell-centres for any i-j-k location
without an actual polyMesh.
STYLE: remove -noFunctionObjects from blockMesh
- no time loop, so function objects cannot be triggered anyhow.
