hle, json, ves, ves0, vgsf, vgsf0, vmu, vss, vss0

Purpose

TEMP2_MOD holds the velocities of rotational mixing at each interface, computed by VCIRC and turned into diffusion coefficients by CODIFF. Shared by 5 routines. It replaces COMMON/TEMP2/ (MHP via Claude, 10/14/26); JSON comes from DIMENSIONS_MOD.

What its variables hold, who sets them, who reads them.

VES, VGSF, VSS, VMU (JSON each): the Eddington–Sweet circulation, the Goldreich–Schubert–Fricke, the secular-shear and the $\mu$-current velocities, set by VCIRC (to 0 first). Read by CODIFF (the coefficients COD, COD2 from the sum VES + VGSF + VSS), CHECKJ (which writes them) and, except VMU, by PUTSTORE and STITCH (the stored model).
VES0, VGSF0, VSS0: the previous iteration's VES, VGSF, VSS, saved by VCIRC from the second iteration on, which then averages old and new values; CHECKJ writes VES0 and VGSF0.
HLE(JSON): a length scale, set to 0 at every interface by CODIFF (its assignments of RMID are commented out); CHECKJ writes it as "LENGTH."

Design

A blanket USE TEMP2_MOD in each routine.

The changes since rp_1

Changed since rp_1. New file: COMMON/TEMP2/ as a module.

That matches COMMON's semantics. 19 MODULE TEMP2_MOD 20C 10/20/26 MHP via Claude 21C code changed to take JSON from DIMENSIONS_MOD instead of declaring 22C a PRIVATE copy here. 23 USE DIMENSIONS_MOD 24 25 IMPLICIT NONE 26 SAVE 27 28 REAL*8 :: VES(JSON) 29 REAL*8 :: VES0(JSON) 30 REAL*8 :: VSS(JSON) 31 REAL*8 :: VSS0(JSON) 32 REAL*8 :: HLE(JSON) 33 REAL*8 :: VGSF(JSON) 34 REAL*8 :: VGSF0(JSON) 35 REAL*8 :: VMU(JSON) 36 37 END MODULE TEMP2_MOD
