Failed to import butterfly

grasshopper butterfly
2

… I tried the following, and the problem as reported above is still not solved:

  1. reinstalled butterfly using the original installer file in the installation package

  2. changed the OpenFOAM version number to v1706+ in the version.py file

  3. there are 43 files in the folder C:\Users#USERNAME\AppData\Roaming\McNeel\Rhinoceros\5.0\scripts\butterfly

  4. now open the outdoor airflow example file, and there is no component with the Failed to import butterfly: red error. But the blockMesh component is not working and is still reporting OF version related error:

    1. Solution exception:Failed to find container id.Do you have the OpenFOAM container running?
      You can initiate OpenFOAM container by running start_OF.bat:
      C:\Program Files (x86)\ESI\OpenFOAM\1706\Windows\Scripts\start_OF.bat

  5. so, update butterfly using the Butterfly (BF::BF) component, and there is a problem, so delete the three butterfly related folder in C:\Users#USERNAME\AppData\Roaming\McNeel\Rhinoceros\5.0\scripts as discussed here

  6. update again, and it works.

  7. now there are 44 files in the folder C:\Users#USERNAME\AppData\Roaming\McNeel\Rhinoceros\5.0\scripts\butterfly, and the newly added file is gradingutil.py

  8. run Rhino as admin again, now the Failed to import butterfly: red error show up for three of the major butterfly component.

  9. So, it seems the butterfly update somehow created some issues here …

appreciate your kind advice on how to solve this issue.

Thanks.
