Troubleshoot

Activate debug logs

When troubleshooting issues in BiRD, we recommend making sure to switch the log level to DEBUG At the top of your script

from bird import logger
logger.setLevel(level="DEBUG")

Unrecognized drag and mass transfer model

[6] --> FOAM FATAL ERROR:
[6] Unknown dragModelType type Grace

This may mean that you are using multiphaseEulerFoam instead of birdmultiphaseEulerFoam

BDOFoam does not compile

birdmultiphaseEulerFoam requires OpenFOAM 9 but bdoFoam requires OpenFOAM 6. Compiling bdoFoam also requires a little more work that birdmultiphaseEulerFoam. Detailed step are discussed here

In the future, we will make sure that bdoFoam works with OpenFOAM 9.
