- The -rotate-angle option allows convenient specification of a
rotation about an arbitrary axis. Eg, -rotate-angle '((1 1 1) 45)'
- The -origin option can be used to temporarily shift the origin
for the rotation operations. For example,
-origin '(0 0 1)' -rotate-angle '((1 0 0) 180)'
for mirroring.

Description
|
|
Transforms the mesh points in the polyMesh directory according to the
|
|
translate, rotate and scale options.
|
|
|
|
Usage
|
|
Options are:
|
|
|
|
-translate vector
|
|
Translates the points by the given vector before rotations
|
|
|
|
-rotate (vector vector)
|
|
Rotates the points from the first vector to the second,
|
|
|
|
-rotate-angle (vector angle)
|
|
Rotate angle degrees about vector axis.
|
|
|
|
or -yawPitchRoll (yawdegrees pitchdegrees rolldegrees)
|
|
or -rollPitchYaw (rolldegrees pitchdegrees yawdegrees)
|
|
|
|
-scale scalar|vector
|
|
Scales the points by the given scalar or vector.
|
|
|
|
The any or all of the three options may be specified and are processed
|
|
in the above order.
|
|
|
|
With -rotateFields (in combination with -rotate/yawPitchRoll/rollPitchYaw)
|
|
it will also read & transform vector & tensor fields.
|
|
|
|
Note:
|
|
roll (rotation about x)
|
|
pitch (rotation about y)
|
|
yaw (rotation about z)
