- can specify rotations that are not "axes" in a compact form:
transform
{
origin (0 0 0);
rotation none;
}
transform
{
origin (0 0 0);
rotation axisAngle;
axis (0 0 1);
angle 45;
}
An expanded dictionary form also remains possible:
transform
{
origin (0 0 0);
rotation
{
type axisAngle;
axis (0 0 1);
angle 45;
}
}
STYLE: verbose deprecation for "coordinateRotation" keyword
- the "coordinateRotation" keyword was replaced by the "rotation"
keyword (OpenFOAM-v1812 and later) but was handled silently.
Now elevated to non-silent.
STYLE: alias lookups "axesRotation", "EulerRotation", "STARCDRotation"
- these warn and report the equivalent short form, which aids in
upgrading. Previously had silent lookups.
