Hi Mike,
thanks for replying. Yeah, my COMSOL model was set around the Geant4 convention of (0, 0, 0).
I’ve returned the Tabulated3d field to default by removing my multipliers and [7.4 6.66 -1.48] is now being displayed by Geant4 as [74 66.6 -14.8] and lenUnit is now centimetre.
I have previously plotted the COMSOL generated field field in Matlab and it looks sensible (see attachment, apologies for arrow heads).
The messages from TabulatedField3D (below) seem correct. So, the field should be visible.
