Non-FEA Design Loads are individual load scenarios defined by the user and manually applied to a Zone or Joint. In other words, these Design Loads are not derived from FEA results. HyperX will Size/Analyze these cases right alongside the FEA-Based Design Loads for each Zone or Joint they are assigned to.
Note
Non-FEA Design Loads do not require a loads processing technique. If just Analyzing/Sizing according to Non-FEA Loads, there is no need to define a Load Property.
There are two categories of Non-FEA Design Loads, each with its own specific subcategories based on the type of Zone/Joint they are defined for: FEA-Like and General User-Defined Loads.
In the case of FEA-Like Design Loads, the user manually defines Zone- or Joint-level force and moment values. These values are treated as a set of Design-To Loads, akin to what is derived after processing FEA-based loads.
The screenshot below shows the inputs required for a panel FEA-like Design Load. Note the force and moment components are the same values that are extracted for 2D elements from FEA.
-
During Analysis/Sizing, the loads from each active Design Load Case are processed within each Zone/Joint and then run for each enabled failure method.
-
FEA-Like Design Load Cases are stored in the Database and therefore can be shared by multiple Projects (see Sharing Properties Between Projects), saved as part of Database Templates, and shared between Databases.
-
FEA-Like Design Load Cases are assigned to Zones or Joints. The selected entities then inherit all load definitions contained in that case.
-
One FEA-Like Design Case can be assigned to as many Zones/Joints as applicable, as long as the Zone or Joint type is consistent with the case type (i.e. a 2D design case cannot be assigned to a 1D beam zone)

There are three types of FEA-like load cases, each corresponding to the type of entity to which they are applied:
-
Panel Loads - in which the user defines force and moment values corresponding to 2D Zones.
-
Beam Loads - in which the user defines force and moment values corresponding to 1D Zones.
-
Joint Loads - in which the user defines force and moment values to be applied to Joints.
-
In the case of User-Defined Design Loads, the user has the freedom to manually define Zone- or Joint-level forces/moments, displacements, or fixed/free conditions. The screenshot below shows the inputs required for a General Panel Design Load. Notice the selection menu, which exists for each load variable, that allows the user to toggle between definition types. Note also that the force and moment components required are the same values that are extracted for 2D elements from FEA.

During Analysis/Sizing, the loads from each active Design Load Case are processed within each Zone/Joint and then run for each enabled failure method.
-
General User-Defined Design Load Cases are stored in the Database and therefore can be shared by multiple Projects (see Sharing Properties Between Projects), saved as part of Database Templates, and shared between Databases.
-
General User-Defined Design Load Cases are assigned to Zones or Joints. The selected entities then inherit all load definitions contained in that case.
-
One Design Case can be assigned to as many Zones/Joints as applicable, as long as the Zone or Joint type is consistent with the case type (i.e. a 2D design case cannot be assigned to a 1D beam Zone).

There are four types of FEA-like load cases, each corresponding to the type of entity to which they are applied:
-
Panel Loads - In which the user defines the load state corresponding to 2D Zones.
-
Beam Loads - In which the user defines the load state corresponding to 1D Zones.
-
Bonded Joint Loads - In which the user defines the load state of a specified Bonded Joint concept. The example below indicates load definition required for a single-lap joint design.
-
Bolted Joint Loads - In which the user defines the load state corresponding to a Bolted Joint.
