The various MSC supplied Application Modules and Application Preferences, as well as user-added code, are listed in the Analysis Preferences menu. An analysis code and an analysis type are specified by the user. For example, the analysis code might be for MSC Nastran and the analysis type STRUCTURAL. The selection can be changed any time during model creation. However, there may be conflicts in the data if the analysis code preference is changed after properties are assigned.

If the intended analysis code is modified, as much data as possible will be converted. If the new intended analysis code has required properties that are not defined, or if data cannot be transferred, a warning message will be displayed.
