Added defaults for package interfaces. Tested for exp(0,2,4).
Moved setting of default values for GM/Redi parameters to gmredi_init()
Added separate initialization routine for pSurf (otherwise known as cg2d_x). This allows easy initial value problem in free surface height (read from file in pSurfInitFile) and helps split up the initializations of "fixed" and "variable" arrays.
Various updates for OBCs and Non-hydrostatic routines. o OBCs now fits into time-stepping properly o div.G has been moved to solve_for_pressure()
Corrected interaction between OBCs and algorithm. The positioning of set_obcs() within the time-stepping sequence is crucial for stable open-boundaries. Forcing the boundaries with time-dependent flow previously led to horrible results...
Added IVDC (Implicit Vertical Diffusion Convection). Also facilitated a "convection counter" that is output through "diags".
Added a parameter "implicitViscosity" to separately control implicit viscosity and diffusion.
Added COS(latitude)^cosPower dependence to viscosity terms. New parameter "cosPower" defaults to 0.0 which removes latitudinal dependence.
Implemented new I/O package (mdsio.F). This package does parallel
I/O in much the same way as dfile.F used to except it uses "direct
access" rather than (f77) unformatted sequential access.
Problems with dfile.F package included:
o unnecessary memory use (each process had two global sized buffers)
o inability to read the files it had written without post-processing
o "tiled" files were tiled by process/thread rather than actual tiles
o created huge numbers of files with no alternatives
Features of the mdsio.F package:
o direct-access binary writes
o no excessive memory use
o ability to read/write from multiple record files
o "tiled" files are based on "WRAPPER" tiles so that the number
and content of files is independent of the number of threads
and/or processes
o option to create single "global" files rather than "tiled" files
o ability to read both "global" and "tiled" files
[Caveat: the tiling of files must match the model tiles]
o checkpoints now use a single file per model section
ie. one file for the hydrostatic model core, one file
for the non-hydrostatic extensions and one file for the C-D
extensions
o the mid-level I/O routines now is broken into more source files
read_write_fld.F supplies basic I/O routines with the same interface
as the original I/O package
read_write_rec.F supplies I/O routines which allow multiple records
write_state.F writes the model state
checkpoint.F supplies the read/write checkpoint routines
All the example input data has had to be modified to be direct-access.
Otherwise only routines that used I/O have been affected and not
all of those have been due to the continuity of arguments in
the read_write_fld.F routines.
What needs to be done? We have to create a suite of conversion
utilities for users with old-style data. Also supply the option
for using old-style I/O, not just for die-hards but for reading
data too extensive to be converted. And more...
Modifications for non-hydrostatic ability + updates for open-boundaries.
o Added "natural BCs" as alternative to "virtual salt flux" o Re-difined precFloat32 and precFloat64 to be 32 and 64 so that their values can be meaningfuly set in the data file o Modified read_write.F to create an exception if readBinaryPrec is not set o Replaced CPP control of viscous BCs with run-time control o Tidied up input-data precision (ie. ini_depths cnh_dbg...) o ini_forcing.F now initialises *all* forcing arrays to zero o Definitively tested verification experiments 0,1,2 and 4 (3 is atmospheric set-up which is in a state of flux)
