Import and Display of the Displacement Models

One result of the stress calculation in the stress analysis package is the displacements based on thermal influences on the whole pipe system. These displacements can be displayed in PDMS.

For each loading case a separate model containing equipment elements with nozzles is created. These models can be displayed together with the original pipe.

In order to read in the displacement files a design database with multi-user write access must be selected. In this database a site (in the example /R2) must be created. The attribute PURPOSE of that site must be set to DISP.

If there is such a site in a read/write database it will be displayed in the form.

It must be taken into account, that the imported models of the loading cases will cause hard clashes inside PDMS. Therefore it is recommended to import the model into database that are not always current, only temporarily to check the loading cases.

The loading case models are based on parameterised NOZZles (in the shape of a dumb-bell). The nozzles represent two adjacent calculation points and the direct line between these two points with two spheres and one cylinder. The "pipe" can also be shown with the insulation. In order to display the insulation the transparency of Obstruction and Insulation should be set to 50% in the central representation form Settings > Graphics > Representation in the main menu of PDMS Design.
