Problem:

How to import loads from AutoPIPE into AutoPIPE Nozzle?

Solution:

Using the procedure here. AutoPIPE Nozzle application is automatically opened and the dialog below will then be displayed. Otherwise, start AutoPIPE NOZZLE, select File> Import AuoPIPE... command.

1. On the "Import AutoPIPE Nozzles" dialog screen, " Select Nozzle PXF file" should have automatically been the filled in with the model name exported from AutoPIPE, ex: Walkthru

User must press on the drop down arrows to choose BOTH a "Select Nozzle ID" and a "Analysis Set Number", as pictured below.

Note:

A. Click on Browse button to open any AutoPIPE PXF file which contains all the nozzle loads, identifier and geometry information i.e 8000 3 control card.

B. Click on the Update button to refresh the Nozzle Identifiers into the drop-down list. This is necessary if the AutoPIPE point names have been renumbered. Note: The current model will be saved before the update operation.

C. The checkbox "Import loads into existing model" by default is not checked. If checked, the program skips checking the AutoPIPE Nozzle.map file in the AutoPIPE Nozzle\project directory for existing model match but instead imports the new loads from Autopipe into the current model. No save operation is performed.

When importing a nozzle from Autopipe, the program checks if this nozzle id name and AutoPIPE model exist in the AutoPIPE Nozzle.map, if it does, the existing model (WNZ???.NOZ) details e.g shell diameter, shell type etc are loaded into AutoPIPE Nozzle before the new loads and nozzle geometry are imported. The model is then saved with the new loads. If the WNZ???.NOZ is not found a warning message is displayed and a new WNZ???.noz file is created in the project directory.

When the "Nozzle ID" and "Analysis Set Number" have been properly selected, press the OK button; nominal nozzle size & thickness and nozzle loads are imported into AutoPIPE Nozzle.

2. Choose from 5 different vessel "Orientation", and press OK button to complete the process of importing nozzle loads from AutoPIPE V8i or higher.

The Nozzle axis is set to either X or –X based on data from the AutoPIPE PXF file i.e near or far points where the nozzle loads are acting at the anchor. The user can modify the nozzle axis from the drop-down list.

Click OK to accept the selected vessel orientation. Th Nozzle Axis and Shell Axis are then set accordingly on theShell tab, or click Cancel to restore the previous axes settings

Note: AutoPIPE Nozzle can only process one nozzle at a time. When completed with the current nozzle, save the file, and then select File> Import AutoPIPE... to select a different nozzle ID to be processed.

Example 1:

Give the following model configuration and results from AutoPIPE:

Loads were exported to AutoPIPE Nozzle:

Press OK button:

Now set the orientation of the nozzle and vessel on the Vessel / Nozzle Orientation dialog,

a. set Nozzle Axis = -X

b. set Orientation = Horiz Vessel #1 / Vert. Nozzle

Press OK button to finish importing the loads, select the Loads Tab

It would appear to the novice user that there is a problem with the imported loads into AutoPIPE Nozzle as they do not match exactly to the same axis directions as in AutoPIPE.

Remember that AutoPIPE will only export loads to AutoPIPE Nozzle using Local Axis orientation,

In this example, the AutoPIPE segment direction is going vertically Down to node point B13, note the correlating local axis direction in the image above.

Note that the image on the Vessel / Nozzle orientation dialog has the same axis orientation as AutoPIPE, but is displaying the negative directions. Therefore, they are equal

At this point it clear to see that

AutoPIPE global +FX = Local -FZ

AutoPIPE global +FY = Local -FX

AutoPIPE global +FZ = Local +FY

Remember that AutoPIPE Nozzle always has the same image on the application screen, therefore the Vessel / Nozzle orientation axis are articulated to match, steps shown below:

In the end, the loads imported into AutoPIPE Nozzle does match the local axis orientation in AutoPIPE.

Note, the user can modify AutoPIPE Nozzle Shell tab, Shell Axis and Nozzle Axis settings, but be warned that these changes does not update the load values already imported. Again, if changes are made to the Shell tab settings mentioned, the user will need to manually update the Loads table accordingly. A new enhancement has been logged for this shortcomings.
