Every node in a model is associated with a coordinate system that, by default, is aligned with the global Cartesian coordinate system. If any of the X, Y, or Z axes of an individual node is rotated, the resulting coordinate system will typically not be aligned with the global Cartesian coordinate system. Using this feature, you can display nodal result rotations either as Euler rotated triads at each node location, or as contours that represent an Euler rotation angle about an individual nodal axis. Boundary conditions are highly dependent upon Euler angles.
To display nodal coordinate systems results:
Highlight the Solution object, and choose one of the following options from the Coordinate Systems drop-down menu. A corresponding object will be inserted in the tree.
Nodal Triads: Displays an XYZ triad at each node representing the resulting rotation of the node's coordinate system compared to the global Cartesian coordinate system. See Rotational Order of Coordinate System Results for details.
Nodal Euler XY Angle: Displays a contour plot representing the magnitude of the resulting Euler angle rotation at each node about the Z axis.
Nodal Euler YZ Angle: Displays a contour plot representing the magnitude of the resulting Euler angle rotation at each node about the X axis.
Nodal Euler XZ Angle: Displays a contour plot representing the magnitude of the resulting Euler angle rotation at each node about the Y axis.
Note: For the Mechanical APDL solver, nodal coordinate systems will not vary from time step to time step.
