A *load case* defines how [load patterns|kb:Load pattern] are applied (statically or dynamically), how the structure responds (linearly or nonlinearly), and how analysis is performed (through [modal analysis|kb:Modal analysis], [direct integration|Comparison between FNA and direct-integration time-history analyses], etc.). For each analysis to be performed, a load case is defined. Each load case may apply a single load pattern or a combination of load patterns. An unlimited number of load cases may be defined, then any set of load cases may be selected for analysis. Once analysis has run, load-case results may be selectively deleted or compiled for output reports.

Specifications for each load case include:

* *Case name*  A unique name is applied to each individual load case to index analysis results (displacements, stresses, etc.), create [load combinations|kb:Load combination], and possibly correlate with dependent load cases.

* *Applied loading*  Load patterns are applied to the structure. In some instances, however, load patterns are not applicable.

* *Analysis type*  Analysis type includes the method (static, [response spectrum|kb:Response-spectrum analysis], [buckling|kb:Buckling], etc.) and the formulation (linear, [nonlinear|kb:Nonlinear], etc.).
