Update notes:
v2.0: 2015 Stable release (v2.0.4):
Update notes:
v1.4: 2014 Stable release (v1.4.0):
- PDF: V2 Manual (October 2014)
- Fixed inflows bug : was not inserting inflow if it failed to reach neutral buoyancy in the daily time step
- Fixed a long standing, unnoticed bug with benthic processing
- Fixed a bug in lake.csv - some columns were always "missing" (introduced by libutil split)
- Fixed minor bug where lake.csv was empty if csv_point_nlevs was 0
- Fixed a bug in initialization that crashed if there were more WQ variables in inflow than in FABM
- Added support for different plots.nml file names - now if a name appears after the --xdisp (without a preceding --) then it is assumed to be a plots.nml filename and is used instead of the default
- Fixed a bug where surface flux was being added twice
- Added support for fonts in plotting
- Fixed plot window name
- Renamed glm variables with FABM in them to WQ instead
- Added outflow output files in the format of inflow files
- Changed &fabm_setup to wq_setup
- If out_dir doesn't exist, attempt to create it
- Added time format option to csv files
- Added passing of bottom_stress to FABM from GLM [NB this is non-functional because GLM does not have bottom stress yet]
- Added benthic light area code
- Preliminary support for non-gui OS-X version. Unfortunately this was broken again when fabm was updated. Although the new fabm will build, the compiler hangs on glm_fabm.F90 trying to load fabm.mod.
- Split glm_model to support non-averaged inflow/outflow and meteo
- Separated from libutil library
- Added scaling factors for met variables other than wind
- Modified the way wind_factor is done, it now is applied when met is read in, rather than everywhere wind is used. This might fix an unknown bug since fabm was using the unscaled value of windspeed
- # FABM mods
- Updated to new FABM as at 20131121
- Added new k_wind variant to aed_utils.F90
- Added support for varied mobility (vertical movement) in phytoplankton
