| Summary | 0004260: Crash during redistribution when using zoneGenerator with loadBalancer | ||||
| Description | Running a case with a zoneGenerator definition in combination with the loadBalancer dynamic mesh solver causes a crash during the mesh redistribution phase. This occurs regardless of the moveUpdate setting (true or false), and the issue is reproducible in both serial and parallel execution of the createZones utility. | ||||
| Steps To Reproduce | 1. Use the aachenBomb tutorial as a base case. 2. Create zonesGenerator with the following cell zone: sphere { type sphere; zoneType cell; moveUpdate true; centre (0 0.05 0); radius 0.025; } 3. Run the zone creation step using the createZones utility (either serial or parallel) 4. Start the simulation in parallel | ||||
| Additional Information | Notably, renaming the zonesGenerator file to createZonesDict (and using createZones without the -zoneGenerator option) avoids the crash, and the case runs without error. | ||||
| Tags | No tags attached. | ||||
|
|
Why do you need to pre-generate the zones (step 3)? Surely the point of the zonesGenerator is to generate and update the zones at run-time. |
|
|
Sure, there is no particular need to pre-generate the zones in this case and I am fine using createZonesDict for my current setup, and it works without issue as I mentioned in the Additional Information section. I just wanted to bring the behavior to your attention in case the crash with zoneGenerator and loadBalancer is unintended. It may be useful for other users or debugging. Thanks! |
