Define Dynamic loads for distributed-load excitations

These steps describe how to define the attributes of the Dynamics subcase and how to add loads.

Define subcase attributes

See Define Response Dynamics result types for instructions on defining the attributes of the Dynamics subcase.

Add loads to the subcase

  1. In the Simulation Navigator, right-click the Loads node under the subcase you are defining and choose New Load and then choose the type of load to add to the subcase (for example, a Force, Moment, Bearing, and so on). Note: Nodal Force Locations generate attachment modes for nodal force excitations. They do not generate the distributed attachment modes and load set needed for a distributed-load excitation. Therefore, if you are adding a dynamic load for a distributed-load excitation, use any load type other than a Nodal Force Location.

  2. Define the load. For example, for information about defining a force load, see Force load.

For each dynamic load you define, the solver generates a load set and distributed attachment mode, which you can then use to apply a distributed-load excitation to the model.

Note:

Distributed attachment modes are not reflected in the count of attachment modes in the Simulation Navigator. You can view information about the distributed attachment modes by right-clicking the Modal Representation node and choosing Information.
