There is always a current load case. This will be the “default” load case unless changed by the user. Any loads and boundary conditions sets created are added to the current load case.
The current load case can be changed in three ways:
• When a new load case is created using the Load Cases Create option, the new load case becomes the current load case if the Make Current toggle is on.
• When a load case is modified using the Load Cases Modify option, the modified load case becomes the current load case if the Make Current toggle is on.
• The current load case can also be changed from the Loads/BCs application .
The current load case affects which loads and boundary conditions sets markers will be displayed. Only those loads and boundary conditions in the current load case can be graphically displayed.
The default load case is static. In order to create time-dependent loads and/or boundary conditions sets, the load case type must be defined as time dependent in the Load Cases application.
If a static loads and boundary conditions set is assigned to a time dependent or dynamic load case, the loads and boundary conditions set will be assumed to be constant with time.
Load case information is permanently stored in the database (unless deleted) and can be modified at any time.
For simple analyses, the Load Cases application need not be used. All loads and boundary conditions sets will automatically be included in the default load case and applied to the model.
