Q: Task stays in "Pending" status for a long time?
A: Tasks are processed in submission order. During peak hours there may be a wait. The table refreshes every 45 seconds automatically; you can also refresh the page manually to check the latest status.
Q: Task status shows "Failed". What should I do?
A: Please check the following:
- Whether the uploaded geometry file format is correct
- Whether the parameter configuration is valid (especially required fields)
- Whether the file content is complete and not corrupted
If everything looks correct and the task still fails, please submit a report via the Feedback button in the bottom-right corner.
Q: When will the ACADE module be available?
A: The ACADE module (aircraft external flow field with boundary layer mesh adaptation) is currently in internal testing. Please stay tuned for announcements.
