[MITgcm-support] z coordinate

[Riema Rachmayani]

dear MITgcm,

first, now i have problem with z coordinate, in my case i have water depth =1000 m, divided become 2 layers, 1st layer is 30 m, 2nd layer is 970m, when describe it in data file 
delZ=30.0,970.0, right?? but i have bad result..from the visualisation of temperature distribution it just look the top of sill, not entire water depth, and when i describe it into 20 layers for each 50m in data file delZ=20*50.0, i have good result for the visualisation, i can see entire water depth, larger number of delz is better?? or i forgot something to change beside change Nr in code/SIZE.h??


second, i've done internal wave verification in nonhydrostatic for MITgcm case with bathyfile =topog.slope, i can see interface profile disturbed by the effect of nonhydrostatic, barotropic tidal and bathy slope, but when i change bathyfile longer, i saw no same effect again, it is matter of initial value of Tref, open boundaries right?? any steps i should do about boundaries or initial value?? what about when i'll use East open boundary, West open boundary??change in obcs_calc.F??


thank you,
regards
rima
