Problem:

The following appears:

why?

Solution:

AutoPIPE dose not use all of the systems resources. Internally it is limited to a percentage of the total system resource available. This message is displayed when the program allocated system resources are almost depleted.

Example: As of Jan 2025, when opening a AutoPIPE model, the database can only use 10 meg worth of system memory. The above message is displayed when the database requirements are getting close to 10 meg of memory consumption.

After encountering this message, the application may experience reduced performance with large models or demonstrate other issues associated with the near depletion of allocated resources (ex. a. sluggish graphics regeneration, b. slow panning or zooming, c. prolonged analysis times, d. the appearance of this warning message, etc..).

Consider using an iterative approach to to resolving this issue by using one or more of the following suggestions. After applying a suggestion, restart AutoPIPE open the model and evaluate if the problem remains. Repeat as necessary.

1. Compact the database.

Tools> model Compaction

Use the application for a period of time to see if the warning reappears.

2. Are Modal or Dynamic analysis being performed?

If yes :

a. Consider using settings that would favor less memory requirements.

example:

i. For Modal Analysis, lower "Maximum number of modes" and "Cutoff frequency (Hz)"

ii. For Time history, consider changing "Analysis steps" and "Output steps" to effectively lower the total "# Time Steps". Also, uncheck "Print Step Results" and suggest reducing the size of the ground motion THL file.

iii. For Response spectrum, consider reducing the size of the defined Spectra files. Also, uncheck Print Modal Results.

b. Reduce the number of mass points per span, Under Tools> Model Options > Edit> set "Mass points per span" = 0, testing to see if this is the culprit. Or reduce to A = Auto.

3. Are TTA analysis being performed?

If yes, suggest reducing the number of data points in the TTA profile or reduce the TTA solution parameters in favor of efficient analysis time.

4. Are one of the following piping codes, ASME NB, NC, or ND assigned to the model?

If yes, review the Stress Summary settings for all Stress levels, again changing settings in favor of a more efficient analysis time.

6. Does your model have Soil properties?

If yes, increase the soil spacing across all SOIL Id's as necessary.

7. Rewrite the AutoPIPE model data base.

This should be considered a Last ditch effort; save the model as an AutoPIPE Batch NTL file and reopen the Batch NTL file. This will rewrite the model's database. See WIKI here.

NOTEs:

1. suggest using a different system name when saving to NTL as the original model will be over written if open *.NTL with the same systemname.DAT file.

2. Also, the user is cautioned when using this sequence of commands that a lot of settings may be changed and it is imperative that the user systematically review the entire model and all settings under Tools> Model Options> General, Edit, and Results. NTL format is very structure and will change some / many original settings to AutoPIPE default settings. Again, use caution and check the model after using this approach.

8. If this continues to occur, log a Bentley Service Request and attach your AutoPIPE *.APC file for review (see AutoPIPE help, search APC)

Notes:

1. If the issue is not resolved by the steps above, please log a new Technical support case, send in your AutoPIPE APC file for review, and add information related to the history of the model; imported portions of the model, large number of Delete commands used, etc..

2. The development team will use a special application to review a model's database and determine if any variables (ex. ntot, lent, lpnd, nsize) are absurdly high.
