- This provides a mechanism for moving mesh patches based on external
input (eg, from an external structures solver). The patch points are
influenced by the position and rotation of the lumped points.
BC: lumpedPointDisplacementPointPatchVectorField
Controlling mechanisms:
- externalCoupler
for coordinating the master/slave
- lumpedPointMovement
manages the patch-points motion, but also for extracting forces/moments
- lumpedPointState
represents the positions/rotations of the controlling points
Utils:
- lumpedPointZones
diagnostic for visualizing the correspondence between controlling
points and patch faces
- lumpedPointMovement
Test that the patch motion is as desired without invoking moveMesh.
With the -slave option, return items from a precalculated table
for the lumpedPointDisplacementPointPatchVectorField BC.
