Interface Settings

Defines various default settings to define how PSI behaves.

Stress Zone Purpose

PSI looks at the zone purpose attribute to find zones containing stress groups. In the example shown, the Stress Zone purpose should be set to PSI to be identified as a stress zone.

Stress Group Colour

Refers to the graphics colour of the current stress group.

Note:

To change the colour of a group, click on the coloured box to display a colour palette with a selection of colours to choose from.

Load Case Colour

Refers to the display colour of the returning load case branches.

Note:

To change the colour of a group, click on the coloured box to display a colour palette with a selection of colours to choose from.

Start Node Number

By default, for any stress pipe, this is the number to start numbering the nodes from.

This is where the increment number between the nodes can be set, by default it is 10 but can be changed to 100 or any other uniform numbering convention.

Note:

For changes to take effect, the stress group has to be refreshed, this is achieved by right clicking on the desired stress group and selecting Refresh Current Group and toggling the Nodes check box on/off.

Stress Ready Attribute

Turns the stress ready checking on/off.

For example, when it is turned on, each branch that is added to a Stress Group will be checked that it is ready to be stressed. This is used in conjunction with an expression which allows the stress ready attribute to be configured. If the stress ready system is used, it prevents branches from being added to a stress group. It does not prevent a stress run.

Max Allowable Movement

The maximum distance that a stressed pipe can be moved when returning into AVEVA E3D™. If any load case exceeds this value then the load case is deemed as invalid and the load case will be deleted. If this event occurs then a warning message will be displayed.

Separate Values/Flanges

Allows connected flanges to be treated as separate rigids. Changing this setting will require the stress group to be refreshed to get a new set of nodes.

Branch Selection

Allows branches to exist in just one or multiple stress groups.

Stress Zone Search

Allows you to set where to search to see where a branch exists. There are two options: All and Current. If the search is set to All then all stress zones will be checked, or if it is set to Current then only the current creation zone is checked to see if the branch exists in another stress group.

Note:

Only active if Single is selected in Branch Selection which means that a branch can only be in one stress group at any one time.

Zero Length Bends

Adding a value for the angle in the text box and selecting the check box stops nodes being created for zero length bends below the specified angle. No nodes are sent to CAESAR II and therefore will not error within CAESAR II.
