Troubleshoot: No Results

You started a Generative Design study, but no outcomes display in the Explore Outcomes dialog.

After you start a study, the process to generate outcomes can take some time, depending on the number of outcomes or generations to be created. The study is complete when the Explore Outcomes dialog displays a green checkmark next to the study name.

The study does not complete

If the Explore Outcomes dialog does not indicate any progress or show any outcomes as they develop, something may be interfering with the proper operation of Generative Design.

An antivirus setting or a firewall can interfere with the ability of Generative Design to communicate with its server. To see if this is the cause of the problem, do the following:

• In the Generative Design server log file, check for a 10053 error (ECONNREFUSED) and errors with dynamic ports, such as 5005. The log file is named refinery-server-log.txt, and it resides here:

  C:\Users\<username>\AppData\Roaming\GenerativeDesign <release>

• If possible at your organization, you can double-check that this is the cause by turning off both the firewall and the antivirus software. Then start the study again. If the study successfully generates outcomes, the firewall and/or antivirus software is the cause of the problem. (After confirming, turn on the firewall and the antivirus software.)

After confirming the cause, use the following work-around:

1. Unblock ports 5000 through 5050.
2. Restart the study, and confirm that outcomes are being generated.

Why this works: The RestDynamoCore processes start on free ports beginning at port 5000. Unblocking those ports allow the processes to run successfully.

The study completes but shows no outcomes

When the study shows no outcomes after displaying a green checkmark, try the following:

• In the Explore Outcomes dialog:
  • Select a study that indicates that at least one generation is complete. This information is displayed in the left pane under the study name.
  • For a scatter plot make sure that the X and Y axes (as well as color and size) are set to the desired settings, and that they make sense for your study.
• For the Dynamo author:
  • If you're using Dynamo for Revit, see if the graph returns results when it's run in the Dynamo Sandbox, for example, using the Data.Remember node.
  • If your outputs are correctly configured in the Dynamo graph but are not listed in the Generative Design in Revit user interface, you may be using lists that are not yet supported by Generative Design. To work around this issue, morph the list data into a scalar value by using the List.Flatten node or a Code Block node (for example, "x=l[0]" in a Code Block node).
