Solution #1

A. Change piping code from B31.3 to B31.1 because buried pipe option is not available in B31.3

B. Open Buried Pipe Options dialog (Tools> Model Options > Buried Pipe Result Options) and Press Ok so that buried pipe options pointer will be updated

Solution #2

A. Change piping code from B31.3 to B31.1 because buried pipe option is not available in B31.3

B. Open Buried Pipe Options dialog (Tools> Model Options > Buried Pipe Result Options) and Press Ok so that buried pipe options pointer will be updated

Answer:

The process of saving an AutoPIPE model (*.DAT) file to an AutoPIPE Batch (*.NTL) file, and then opening the *.NTL file in AutoPIPE to create a new *.DAT file is referred to by us as "round tripping a model"

Information is saved to the AutoPIPE model *.DAT file in a database format with very specific settings and arrangement of data. The AutoPIPE BATCH file (*.NTL) is data written out from the database into a specific formatted text file. When the NTL file is opened in AutoPIPE, the model is created based on the NTL file settings. Because of translating data from DAT to NTL back to DAT, some data is updated with current library information, not exported from the DAT to the NTL file correctly, or other unknown issues. This is why it is VERY VERY IMPORTANT to follow this procedure:

1. Open original AutoPIPE model DAT file (Test.DAT)

2. Run an analysis.

3. Select Results> Output report> ensure all sub reports are checked ON,(except “Sort Stresses” should be turned OFF), save Test.OUT.

4. Select File> Save As > AutoPIPE Batch (TEST-1.BAT)

5. Select File> Open> AutoPIPE batch (*.NTL)> select file (ex.Test-1.BAT)

6. READ and understand any reports that is automatically displayed (ex. CHK, MSG, etc..)

7. Select Results> Output report> ensure all sub reports are checked ON,(except “Sort Stresses” should be turned OFF), save Test-1.OUT.

8. Use an application (i.e. Ultra Compare, Beyond Compare (free on internet)) to compare both Test.OUT and Test-1.OUT to CLEARLY see the differences.

9. IN MOST CASES, the new DAT file will need to be updated to match the original DAT file.

Again, it is very important to perform this process of file comparison and to thoroughly review the new DAT file to be sure of model settings.
