Getting up and running - dynamo butterfly

Is there current guidance on getting started with butterfly in dynamo?

Ive followed the videos on the Ladybug site on getting started with butterfly and also on Github. The GitHub approach uses blueCFD, while the Ladybug video suggests OpenFOAM and Docker.

Ive managed to amend the path in the ‘import and prepare py code’ so it points to where Dynamo 2.1 installs the Butterfly package. I can create butterfly geometry and cases but i cant get past errors with the blockMesh node: “Error: No machine name(s) specified and no “default” machine exists” - it appears in the error watch node “your OpenFOAM installation is not working correctly or the VM is not running”

Can anyone offer advice how to get the outdoor_study example file up and running?

Thanks in advance
