8.1.3 Custom Cost Functions

This section (very much a work in progress...) pertains to the special cases of cost_gencost_bpv4.F, cost_gencost_seaicev4.F, cost_gencost_sshv4.F, cost_gencost_sstv4.F, and cost_gencost_transp.F. The cost_gencost_transp.F function can be used to compute a transport of volume, heat, or salt through a specified section (non quadratic cost function). To this end one sets gencost_name = `transp*', where * is an optional suffix starting with `_', and set gencost_barfile to one of m_trVol, m_trHeat, and m_trSalt.


Table 8.6: Pre-defined gencost_name special cases (as of checkpoint 65z; section 8.1.3).
