Import support for Abaqus load cases

The software provides initial import support for the Abaqus *LOAD CASE and *END LOAD CASE keywords. In Abaqus, a load case refers to a set of loads, boundary conditions, and base motions that define a particular loading condition. For example, in a simplified model, the operational environment of an airplane might be broken into five load cases: (1) take-off, (2) climb, (3) cruise, (4) descent, and (5) landing.

You can use this initial support to import load cases that are associated with static perturbation steps.

• If the input file contains a single load case in one solution step, the software imports all loads and constraints in the load case and associates them with the solution step in the Simulation Navigator.

• If the input file contains multiple load cases in one solution step, the software imports all loads and constraints in the load cases. Each imported load or constraint is named after the associated load case and step number, such as Boundary3_in_LoadCase2_Step5. Only loads and constraints in the first load case of the step are associated with the solution step in the Simulation Navigator.The software places the loads and constraints from all subsequent load cases in either the Load Container or the Constraint Container in the Simulation Navigator. You can then add these loads and constraints to the appropriate solutions or solution steps.

For example, you import an Abaqus input file that contains two static perturbation steps, and each step has two load cases:

• Solution Step 1: LoadCaseA and LoadCaseB

• Solution Step 2: LoadCaseC and LoadCaseD

During the import process, the software creates two steps in the Simulation Navigator. The loads and constraints associated with load cases A, B, C, and D are imported as follows:

• All loads and constraints from load case A and C are imported and associated with steps 1 and 2, respectively. This occurs because load case A and load case C are the first load case in each step.

• All loads and constraints from load cases B and D are imported and placed in the Load Container or the Constraint Container in the Simulation Navigator.
