Hi,
I reinstalled all few times, and now it all seems to work without errors following this (Openfoam v1612+, v1706 or v1712 and VM virtualbox 5.x.xx ? how to manage it. · Issue #349 · ladybug-tools/butterfly · GitHub) and updating the BF components and folders. Therefore I now have: Latest BF, OF v.1706, VM 5.2.8 and the Docker Toolbox has been automatically updated to 18.05.0-ce. Followed all videos to set ok the VM, so no errors appear anymore anywhere.
However, I still have the same issue with vectors, please can you look at my post:
Many thanks. V.
