awiesm3 links: correct feom→atm neighbour count and add R→RnfA link - #56
Merged
Conversation
Match the awiesm3 (N56) namcouple: the feom->atm direction (SST/ice/ currents) uses GAUSWGT U with 9 neighbours (1 9 2), not 25; and the runoff/calving atm->mapper link (R<nn> -> RnfA, GAUSWGT D 1 25 0.1) was missing. awiesm3_feom_links now returns the full 5-link set. Add submit_weightgen_..._regen.sh to regenerate just the two changed links onto an existing weight set.
The 9-neighbour default (90b1eec) is right for high-res atmospheres (TCO639) but broke TCO95/A096, whose deployed namcouple uses GAUSWGT U ... 25. A regen with 9 emitted rmp_feom_to_A096_GAUSWGT_9.nc, so OASIS fell back to a stale full-mesh _25 -> MCT column-count mismatch (208296 vs 211567) at the mesh increment. Key feom->atm on atm_grid: A096 -> 25 neighbours, else -> 9 (default).

Follow-up to #55 (which merged the TCO639/NEXT config + weight-gen tooling). These two commits landed on the branch afterwards and carry the actual coupling-correctness fixes, validated against the awiesm3 N56 namcouple + its rmp files:
