Nonlinear Options controls analysis operations such as generating intermediate results from nonlinear analysis. The Nonlinear Options allows Nastran to generate and display intermediate results during the analysis. These options must be turned ON before the analysis is started.
Generate Intermediate Results: When this option is checked, the solver generates .FNO files for each increment that can be loaded while the analysis is being run. When the analysis is completed, these intermediate .FNO files are compiled into one.
Load and Display Intermediate Results: This option works in conjunction with Generate Intermediate Results and thus, is only available when that option is checked. The incremental results are automatically loaded into the tree under Subcases and can be viewed until the next increment has been solved. This is shown in the example below.
