RotationAngle

Compute the field of angular rotations of points around an axis defined by an origin point and a direction vector

Overview

This AuxKernel computes the rotation angle in radians around an axis given by a reference point (the origin) and a direction vector for every node. The vectors from the origin to the undisplaced node and from the to the displaced node are computed. The displaced point is determined by adding the displacements components to the undisplaced node location. Projection of onto the normalized direction are then subtracted from .

The angle is computed as

If the denominator of this fraction is too small, zero is returned as the angle. The sign of the angle is determined by comparing the cross product of the projected vectors to the direction vector . Right hand rule applies.
