17.14. Project Settings

The project settings contain all settings and customization of a project. A dialog to modify the project settings can be accessed in two ways:

  1. Select "Project | Project Settings..." from the top menu

  2. Select a project's root node in the Model Browser and choose "Project Settings..." from the context menu

The project settings dialog itself is divided into different categories each providing an individual settings page. Here is an overview on the different settings:

17.14.1. Auto-counter Patterns

Auto-counters are available for a number of elements, e.g. for the hazardous events (scenario entries) in the hazard analysis, FTA events, safety requirements, functions, and so on. Note that not all elements in the tool have auto-counters and if an element does not appear in the list, it cannot have an auto-counter ID.

By clicking into the column "Pattern" you may modify the default pattern according to your needs. An auto-counter pattern is using the following format:

[<text>] '{' 'ID:' <format> '}' [<text>]

where <format> is a sequence of zeroes ('0') defining the character length of the ID reference part.

Examples:

  • Pattern: HE{ID:000} resulting values: HE001, HE120

  • Pattern: RQ{ID:0000}-Safety resulting values: RQ1001-Safety, RQ0001-Safety

  • Pattern: {ID:00} resulting values: 01, 10

If you do not want IDs for the elements to be automatically assigned, simply put in an empty string in the pattern field.

In the remaining column you may specify the current starting value for the selected counter. The next creation of an object will use this pattern/number. The new starting value will be in effect after saving the modified auto-counter settings. Note that existing elements will not be touched when changing the pattern, only newly created ones will receive the given pattern/number.

You have an option to prevent the assignment of duplicated IDs via the option shown above the table. If the option is enabled, the next free number pattern will be effectively used as new ID. That means, the value given is actually the start point to search for the next unassigned ID. If the option is disabled, changing the starting value to a smaller value as the current settings may result in duplicated IDs since no check is performed when an element is created. The default is ON to prevent duplicated IDs.

Note that it is also possible to define more complicated and hierarchical auto-counter patterns. However, expert knowledge about the internal meta-models of medini analyze is required in order to do so. Please contact the Ansys support team to inquire more details.

17.14.2. Failure Rate Catalogs

In this category you can specify which failure rate catalogs (handbooks) shall be used for the project. After clicking on "Add" all available catalogs are shown, after selecting the desired one and clicking on "OK" the catalog will be made available in the project.

Supported standard prediction models include the Siemens-Norm 29500 (versions 2011 and 1996), the Military Handbook 217F (Notice 2), the FIDES Guide (2009) and the IEC TR 62380 (same as: RDF2000 issue 2003, UTE-C 80-810). Please contact ANSYS Germany GmbH in order to obtain information about other standards and customization of prediction models according to corporate standards.

Please note, as different catalogs may result in different FIT failures for the same type of element, the concurrent usage of multiple catalogs may require additional alignment factors.
