Boundary Change Assignment to Load Cases/Analyses
|
|
|
Different load (analysis) cases can retain separate boundary conditions within a model. Even in the case where static analysis and dynamic analysis are associated with different boundary conditions, the two analyses can be carried out within a same model without having to make two different model files.
Analysis procedure for assigning different boundary conditions to Load Cases/Analyses is as follows:
1. Define as many Boundary Groups as required for different load cases or analyses, in Model>Group>Define Boundary Group.
2. Define Boundary Conditions and Load Cases.
3. Apply Loads.
4. Assign different Boundary Groups to Load Cases/Analyses using 'Boundary Change Assignment to Load Cases/Analyses'.
5. Perform analysis.
6. Review analysis results. |

Data Selection
The types of defined boundary conditions, which can be applied to different load cases, are listed.
Note
Boundary Group Combination
Boundary Group List
Boundary condition groups selected in Data
Selection to the left are listed.
Name
Name a Boundary group combination, which
will be applied to a load case. Having
named a Boundary group combination, select desired boundary groups from
Boundary Group List, and click
Load Cases & Analyses
Load combinations of static analysis and
analysis types are listed. In
the case of static analysis, click
Boundary Group Combination
Select a Boundary group combination (by clicking in the right end of the entry field) to be applied to the static load case or analysis type to the left. If Unchanged is selected in a construction stage analysis, the boundary condition corresponding to the final construction stage is used. If Unchanged is selected in an analysis without construction stages, all the entered boundary conditions are used.
Constrain DOF associated with Specified Displacements/Settlements by Boundary Group Combinations
In a Specified Displacements or Settlements analysis, the degrees of freedom at the corresponding nodes are internally constrained and treated as supports, and forced displacements are assigned. If this option is selected (checked on), the internal DOF constraints are included in only the boundary group combination corresponding to the Specified Displacements/Settlements.
