The final step in the model building process is to apply constraints and forces and to create or assign coordinate systems. Before you apply loads, create a load collector. Loads are displayed in the color assigned to the load collector. The size of loads and constraints is based on model units and can be modified from within the boundary condition panels.
All loads are stored and displayed in the global coordinate system. Depending on the analysis code being used to calculate results, the loads are transformed appropriately to any local nodal output coordinate system.
The following load types are currently supported:
Accelerations |
Applies an acceleration at a node. Accelerations are displayed as a single-headed arrow with an optional label, A. The label may also display the magnitude of the acceleration. |
Constraints |
Applies a constraint or enforced displacement at a node. Constraints are displayed as a triangle with an optional label that displays the degrees of freedom effected by the constraint. |
Equations |
Applies a general equation constraint between nodes. Equations are displayed with the label, EQ. |
Fluxes |
Applies a flux load at a node. Fluxes are displayed as a thick arrow with an optional label, flux. The label may include the magnitude of the flux. |
Forces |
Applies a concentrated force along any user-defined vector at a node. Forces are displayed as a single-headed arrow with an optional label F. The label may include the magnitude of the force. |
Moments |
Applies a concentrated moment about a user-defined vector at a node. Moments are displayed as a double-headed arrow with an optional label, M. The label may include the magnitude of the moment. |
Pressures |
Applies a pressure on an element or geometry. Pressures are displayed as a single-headed arrow with an optional label, P. The label may include the magnitude of the pressure. |
Applies a temperature constraint at a node. Temperatures are displayed as a straight line starting at the node at which the temperature is applied extending upward, with an optional label, T. |
|
Applies a velocity at a node. Velocities are displayed as a single-headed arrow with an optional label, V. The label may include the magnitude of the velocity. |
