How to access/read the state variable (m_epdev) from inside the Fish UDM in FLAC for various grid zones, like the central zone (2, 2) and adjacent zones (3, 2), (1, 2), (2, 3), and (2, 1), at each iteration step?

(1,3) (2,3) (3,3)

(1,2) (2,2) (3,2)

(1,1) (2,1) (3,1)

Required: state variable (m_epdev) value at each zone at each iteration step inside Fish UDM.

A fruitful reply will be highly appreciated.
