The Results grids and Output report, Code stress results are completely blank, pipe is grey, as seen below:
Why and how to avoid?
There are 2 known reasons why the Results grids may be blank:
1. Under Tools> Combinations> there are no Combinations listed.
2. Piping is set to Rigid
With the model open in AutoPIPE select Tools> Model Options> Combinations> Select the :
If no combinations are listed then the Code Stress tab of the Results grids will be blank too. There must be at least one or more combinations listed in order to display information in the Results Grids.
Close the results dialog screen and look at the Look at the model, is there any PURPLE (magenta) colored pipe indicating Rigid properties:
As shown in the image above the entire system is covered with Rigid pipe properties. This is further confirmed by looking at the "Rigid Options" tab on the input grid.
AutoPIPE does not display stresses for rigid pipe components except Tees (only if Tools> Model Options> Results> Show rigid tee stress is enabled).
In order to see stress results for piping, User must Delete rigid options from that piping selection. (ex. highlight piping with rigid options, use Delete> Rigid Options).
Look again at the results Grids with out changing any other settings,
Now the code stress tab displays stresses as it should for pipe without rigid properties.
Conclusion, if your entire model is covered with rigid properties the Code Stress Results Grids & Output Report will be blank.
