In this section, we cover aspects of setting up and performing the analysis that are specific to nonlinear analyses. Much of the setup process, types of elements, material models, analysis parameters, and more are also common to other analysis types, such as linear analyses. Therefore, first check the General Information (Common to Multiple Analysis Types) section of the Help. If an item pertains to two or more analysis categories, it will be covered in the General Information section. Otherwise, if an item only pertains to a specific analysis type, it will be covered within the Analysis-Specific Information section of the Help.
In some cases, a particular topic might be addressed in both the General and Analysis-Specific sections. This can occur when an item is applicable to two or more analysis types and there are similarities or overlap between them - which will be covered in the General section - as well as significant differences between the analysis types, which are best handled in the analysis-specific section.
