ENH: foamyHexMesh: Made default region volume type that of it's parent
Foamy surface conformation entries have a "meshableSide" entry which
controls which side of the surface is to be meshed. Typically this is
set "inside" for boundaries and "both" for baffles. A sub-region's
default entry is now taken from it's parent, rather than a specific
value (it was "inside"). This is consistent with how other entries are
handled.
surfaceConformation
{
locationInMesh (0 0 0);
geometryToConformTo
{
baffle
{
featureMethod extractFeatures;
includedAngle 120;
meshableSide both; // <-- per-surface setting
regions
{
disk
{
meshableSide both; // <-- per-region setting*
// *in this example, this entry is not needed, as it
// is taken from the per-surface setting above
}
}
}
// ...
}
}
ENH: foamyHexMesh: Added (reinstated) baffle patches
A patch can now be assigned to a baffle surface. This assignment will
take precedence over any face-zones.
surfaceConformation
{
locationInMesh (0 0 0);
geometryToConformTo
{
disk
{
featureMethod extractFeatures;
includedAngle 120;
meshableSide both; // <-- baffle
patchInfo
{
type wall;
inGroups (walls);
}
}
// ...
}
}
STYLE: foamyHexMesh: Switched off output of all the secondary meshes
