Application of Loads to Geometry

You can apply loads to geometrical entities in a way similar to the manner in which loads are applied to mesh. The process includes two basic steps.

1.	Creating a load collector by using the Collector panel.

2.	Applying loads to the geometry using one of the following panels on the Analysis page: Forces, Moments, Constraints, Pressures, Temperatures, Flux, Velocities, and Accels.

To apply a load to a geometrical entity, first create a load collector in which the loads applied to geometrical entities will be stored. Next, access a HyperMesh load panel (such as Forces, Constraints, etc.) located on the Analysis page, and choose the create subpanel. Third, select a geometrical entity on which the loads will be applied (points, lines, or surfaces) using the panel selection box, define the load or boundary condition parameters in the same way you would for the application of the load or boundary condition on a FE mesh entity (such as a node), and click create. HyperMesh stores the loads/boundary conditions in the database and displays them in the graphical window.

The following chart specifies the geometrical entities to which loads can be applied, in each of the load application panels listed above.

Panel	Geometrical Entities
Accels	points, lines and surfaces.
Constraints	points, lines and surfaces.
Flux	points
Forces	points
Moments	points
Pressures	surfaces nodes on edge: lines (for 2-D solid elements) nodes on face: surfaces (for 3-D solid elements)
Temperatures	points, lines and surfaces.
Velocities	points, lines and surfaces.

Refer to the specific panel for detailed information about creating, reviewing, and updating loads and constraints.
