Issue
In 6.12.0002, the u_z column contains concatenated strings like '0.047897309064865110.04789730906486511...' instead of numeric values. This worked fine in 6.11.
Question
Was there a change in 6.12.0002 to how STATIC_ANALYSIS_SURFACES_LOCAL_DEFORMATIONS_GRID_POINTS_TABLE returns the u_z column? How can I get numeric values instead of concatenated strings?
Or is this just a bug?
The results are present in the RFEM6 app UI.
VS Code recognises all the commands (I've noticed that previously when updating the names of certain api calls have changed, so thats the first thing I want to rule out).
I am a glass half full type of guy, so on the bright side at least the error creates quite a cool pattern.
