[Question] Is the ExternalFieldGrid functionality fully implemented in the current release?

[ecustfr]

Hi developers, I am trying to use an external potential field via a .cube file. However, I encountered an "Unknown input" error when passing ExternalFieldGridFileName in the JSON config, even though I see the relevant code in the source files.

Enviornment

• Version: 3.0.14
• OS: Windows11
• Code Reference: I found the parsing logic in forcefield.cpp around line 450, and the key in ForceField::options.

Error Message: [ForceField Error] : Unknown input 'ExternalFieldGridFileName'

Question

1. Is this feature included in the pre-compiled Anaconda/Conda-forge package?

2. If I want to use this now, should I build from the latest master branch instead of using the Conda version?

Best regards, ecustfr
