|
Applied Force (Rigid Connector) to apply a force in given point.
|
•
|
Applied Moment (Rigid Connector) to apply a moment.
|
•
|
Mass and Moment of Inertia (Rigid Connector) to add extra mass and moment of inertia in a given point.
|
•
|
Spring Foundation (Rigid Connector) to add a translational or rotational spring or damper in a given point.
|
•
|
For Automatic the center of rotation is at the geometrical center of the selected points. The constraints are applied at the center of rotation.
|
•
|
For Centroid of selected entities a subnode for selection of the points is added to the Model Builder. The center of rotation is located at the centroid of the selected points, which do not need to be related to the points to which the rigid connector is attached. As a special case, you can select a single point, and thus locate the center of rotation at a certain point.

|
For User defined, in the Global coordinates of center of rotation XC table enter coordinates based on space dimension.
|
•
|
For 2D components, the Constrained rotation and Prescribed rotation at center of rotation is always about the z-axis, so no component selection is necessary.
|
•
|
For Prescribed rotation at center of rotation enter an Angle of rotation φ0. For 3D components also enter an Axis of rotation Ω for the x, y, and z coordinates.
