  • Switched build system from CMake to Makefile.

08/26/2013

  • File and path name-lengths have been made uniform. There are three preprocessor macros, located in 'variab.h' and 'variabex.h' called:
    • FNAME_LEN : Length of filenames. Set currently to 80.
    • PNAME_LEN : Length of paths/directory names. Set to 201.
    • PFNAME_LEN : Max length of fully qualified path+filenames, this should be set equal to FNAME_LEN + PNAME_LEN, currently set to 281. To declare a new string, for say a filename, do the following:
      char filename[FNAME_LEN];
  char pathtofile[PNAME_LEN];
  char fullfilename[PFNAME_LEN];

6/21/2013

  • Added added glacierwide cumulative balances to areamean.txt; increase array sizes of names in variab.h Purpose: allow comparison e.g. with GRACE time series; no change in input.txt, column is added to areamean.txt; Before: mass balance only computed if if( ((winterbalyes == 1) && (summerbalyes == 1)) || (maxmeltstakes > 0) ), NEW: if condition removed.

5/23/2013

  • Added Skin-Temperature calculations.

11/4/2012

  • Fixed mismatching declarations in headers.

8/31/2012

  • Configuration filenmae changed from input.dat to input.txt.
  • Added sample shading.txt shading configuration file.
  • Added Matlab visualization functions inputreadagrid.m and grids2diff.m,
  • Updated Matlab vis tool ``grid.m```

8/28/2012

  • Added sample ```input.dat``
  • Added Matlab grid visualization tool.

Major changes since 11/2011

  • Github hosting!

  • Executable rename:

    • degree is now known as the Distributed Enhanced Temperature Index Model (DeTIM), and has executable detim

    • meltmod is now know as the Distributed Energy Balance Model (DEBaM), and has executable debam

  • Build system in place! MeltMod now uses cmake to configure its builds.

    • Adds portability, cmake generates makefiles with the current environment in mind.
    • Out of source builds: Cmake will build everything in a folder outside of the source tree, and thus keep the source tree unmuddied by built files.
    • All of the relevant tools: ascigrid/gridasci/shading can be build via the same cmake build system
    • That being said, there have been some issues with cmake. In particular, since meltmod's code contains many circular dependencies, these can cause the model to fail to build unexpectedly. (See issue #16 for some discussion of this)

  • Multiple headers: every source file now has its own header file, which is included where needed.

    • Speeds up compile time when changes occur only in a few files
    • Makes the control structure of the program more clear
    • Allows us to make certain functionality more modular

  • Bug fixes: closed the following issues

    • issue #10 : readprecipindexmap was reading the wrong file, this is fixed
    • issue #11 : shayes is turned off when executing the temperature index model
    • issue #12 : methodsurftemp is immediately set to 1 when running the temperature index model, this was happening later, and screwing up some initialization parameters
    • issue #13 : fixed typo in snow-cover initialization
    • issue #14 : fixed bug in simulation mode, wherein large arrays were getting allocated but never used

Which brings us to...

  • Project Reorganization:

    • All model source files are now located in the src/ folder in the project root
    • Utility programs related to the project are located in the util/ folder
    • Tests and their related file are located in the test/ folder

  • Code reorganization

    • All functions relating to matrix and tensor manipulation have been moved into it's own file: grid.c/h and included where necessary. Before, these were spread through a few different files, having them in one place makes sense.
    • issue #9: Redundant long ints nrl,nrh,ncl,nch,ndl and ndh used for matrix/tensor sizing were removed, matrix allocation and deallocation now take integers as arguments.
