v21 v22 17 17 ==== Limitation ==== 18 18 * It is not suitable if high frequency coupling is needed. Because the model need to be stop each time you want to couple ocean/ice sheet. 19 * It not a conservative method (NEMO is creating/losing volume/mass/salt/heat at the coupling time step if the geometry change). I.e., under a pure dynamics ice sheet advance, your mean ssh will stay constant. An option has been added to reduce the unbalance to 0 after a certain amount of time step (ie we apply the total correction over X time step) .19 * It not a conservative method (NEMO is creating/losing volume/mass/salt/heat at the coupling time step if the geometry change). I.e., under a pure dynamics ice sheet advance, your mean ssh will stay constant. An option has been added to reduce the unbalance to 0 after a certain amount of time step (ie we apply the total correction over X time step), however, this option could be unstable (EXP3 ISOMIP+ very unstable with this option, EXP4 run 10 years without any issues). 20 20 21 21 ==== Method ==== … … 60 60 61 61 ||NVTK Tested||'''YES'''|| 62 ||Other model configurations||'''ISOMIP+ EXP 2 and 3'''||63 ||Processor configurations tested|| [ Enter processor configs tested here ]||62 ||Other model configurations||'''ISOMIP+ EXP 3 and 4'''|| 63 ||Processor configurations tested|| 8x4 and 4x8 || 64 64 ||If adding new functionality please confirm that the [[BR]]New code doesn't change results when it is switched off [[BR]]and !''works!'' when switched on||'''YES'''|| 65 65 … … 72 72 73 73 === Bit Comparability === 74 ||Does this change preserve answers in your tested standard configurations (to the last bit) ?||'''YES (ISOMIP+ EXP 4'''||74 ||Does this change preserve answers in your tested standard configurations (to the last bit) ?||'''YES (ISOMIP+ EXP3 and EXP4'''|| 75 75 ||Does this change bit compare across various processor configurations.
