Hi All,

I get these 2 errors on the Blockmesh component when Write is toggled.

Newest version of butterfly and BlueCFD environment is ready.

Please help.

It is a common question about the version of BlueCFD-core. Butterfly only support BlueCFD-core 2017-1 Version, not support 2020-1 version. You should uninstall 2020 version and install the 2017-1, reboot the rhino and computer,butterfly will work fine.
