Pipe Stress Interface - R2 User Guide

Thermal Displacements : Import Displacement Models

Creates a 3D model for each defined loading case in the Rohr2 result file. The 3D model consists of Nozzles that indicate the displacement of the pipe system and can be displayed together with the original pipe system.

For each loading case of a calculated pipe system, Rohr2 writes one ASCII file with the extension .r2disp to the transfer directory. The files contain positions, with movement in X, Y, and Z directions, for each calculation point.

The files are displayed in the Import Displacements part of the AVEVA Pipe Stress Interface - R2 window and sorted by pipe systems and respective loading cases. The list can be refreshed.

Select the loading cases to be imported and click Load Cases to import files to the database.

The example below describes a created hierarchy:


Type	Name	Description
SITE	/DISP
ZONE	/DISP_28MAW30	The ZONE element contains all loading cases of the 28MAW30 system.
EQUI	/DISP_28MAW30_DL	The EQUI element contains the DL loading case.
SUBE	…/F0HAC10BR011/B1	The SUBE element contains the /F0HAC10BR011/B1 branch of the DL loading case.
NOZZ	…/F0HAC10BR011/B1_260-280	The NOZZ element represents the connection between calculation points 260 and 280.

After importing the loading cases, the Import Displacements part of the AVEVA Pipe Stress Interface - R2 window is updated. The Representations part of the AVEVA Pipe Stress Interface - R2 window is populated with the content of the database.

Imported files are renamed from .r2disp to .r2dispold.

Imported loading cases are displayed per pipe system. For each pipe system, a single loading case and all branches of that system are listed. The display of loading cases can be switched on and off and superimposed with the original branch. Colours can be adjusted individually.

Only selected branches in the branch list are displayed in the 3D view. Select a system to update the 3D view with all system branches.

The example displays a superimposed pipe with calculated load cases.
