Analyses

This section first provides information on the way to define and run standard analyses such as static, quasi-static, dynamic and modal analyses, VIV prediction, and API RP 16Q checks for drilling risers.

It also details all the types of analyses that are available, lists related input data and the different numerical parameters to be defined depending on the analysis type.

Note

In the following, "standard analysis" means any type of analysis that may be solved with the FE engine. Standard analysis does not include fatigue analysis which must rather be though of as an advanced post-processing task.

Once you have defined a number of model components and linked them together, you may define one or several analyses that will be included in the model file. The GUI allows you to define several analyses and keep all of them within your model file - this is what we call project-oriented GUI.

Note

Getting several analyses all included in the model file ensures that changes brought to the model component throughout the project will be correctly accounted for within all load cases.

The various analyses that you have created are listed in the model browser in the Analysis Sets folder. The analyses are grouped together into Analysis Sets.

The default set of analyses is labelled Default, and may contain any analysis you define.

The other Analysis sets are groups of analyses that can be linked to Environment Sets or Wave sets. The analyses contained in these sets may only differ by the environmental loadings or by the wave that is considered.

The process for creating a new analysis depends on whether you create a new individual analysis or a new set of analyses. The basic principles however remain almost identical in both cases : each analysis may be thought of as a list of model components linked together, further associated with several calculation parameters - among which the most important is the type of analysis.
