      Adds version numbering to the repository · b6c48e5a
      Benjamin Storer authored
      The file VERSION now records the MAJOR_VERSION, MINOR_VERSION,
      and PATCH_VERSION.
      To update the version number, the user only needs to modify the
      appropriate lines in VERSION.
      
      Makefile has been updated to automatically pass the version
      information through compiler flags.
      
      BaseCase.cpp has been updated to add a print statement into the
      initialization function. By default, every casefile that uses
      BaseCase will now print the SPINS version with which is was compiled.
      This should help avoid issues with mis-matched versions.
      
      It will appear in the output as:
      SPINS Version 1.0.1
      
      The starting version is set to 2.0.0
      
      StackOverflow has a nice summary of when to change which version number
      (https://stackoverflow.com/questions/3826580/what-rules-does-software-version-numbering-follow)
       - Major version numbers change whenever there is some significant change
      being introduced. For example, a large or potentially
      backward-incompatible change to a software package.
       - Minor version numbers change when a new, minor feature is introduced or
      when a set of smaller features is rolled out.
       - Patch numbers change when a new build of the software is released to
      customers. This is normally for small bug-fixes or the like.

      Refactor Science.cpp to split functions into separate files. · dffa6f21
      Benjamin Storer authored
      === Science ===
      The directory Science/ now contains files corresponding to
      the various functions in the now-removed Science.cpp.
      
      Filenames correspond directly with the function name, and each
      file contains only one functions, with a few notable exceptions.
       - Science/get_quads.cpp contains get_quads_x, get_quads_y, and get_quads_z
       - Science/compute_background_PE contains the helper function
      compare_pairs
      
      The global variables _quadw_x, _quadw_y, and _quadw_z are declared as
      extern in Science.hpp and declared in Science/compute_quadweights.cpp
      
      === Makefile ===
      The Makefile has been modified accordingly. It now automatically detects
      all Science/*.cpp files and includes them in the compile recipe.
      
      The Makefile has also been tidied up a little bit by defining a variable
      SPINS_BASE which points to the core files.

      Modify make_deps to check out libraries from UWGit · a55e544e
      Christopher Subich authored
      With the retirement of belize, which formerly hosted a fixed
      copy of the dependency libraries, make_deps.sh would no
      longer download and build said libraries.
      
      These libraries are now instead hosted in a dedicated
      repository at UWGit, so make_deps.sh has been changed to
      clone this repository.

      Update map_iwave case to use new diagnostics · e6b803fd
      David Deepwell authored
      This case has uncovered that the BPE calculation returns
      incorrect values when a Chebyshev grid is used on a field scale.
      The BPE calculation uses the quadrature weights as the volumes
      of each cell. This is true when the grid is regular, but incorrect
      for Chebyshev grids.
      
      To first approximation the Cheb quadrature weights are close to
      the volumes of the cells. This leads to the BPE calculation
      being accurate to 8 significant figures. 8 sig figs is not enough
      on fields scales since the magnitude of the PE can be very, very
      large. The difference of the BPE from the PE can thus be smaller
      than these 8 sig figs.

      Update gravity_current to only use full zgrid · e938e1be
      David Deepwell authored
      The full xgrid and ygrid are unnecessary since x and y only
      depend on a single variable (or index - ii for x, and jj for y).
      The variables xx and yy can be used instead of xgrid and ygrid,
      respectively. Creating the full grids for these fields is a
      waste of memory.

      Simplify GMRES dot products; fix convergence errors · 8ae27fe5
      Christopher Subich authored
      This commit amends Cheb_2dmg::resid_dot (dot-product of
      residual vectors in the context of the 2D GMRES/multigrid
      iteration) to perform the dot-product in the simplest way,
      as a sum over grid elements.
      
      Before this, the code (which is left in the file but
      disabled by #if 1 / #else) tried to be clever and
      evenly-weight contributions from the interior, the boundary
      conditions, and the mean-pressure error (if the problem was
      indeterminate).  This evidently caused the long-standing
      problem of the GMRES inner iteration being far more
      optimistic about error (as reported by LAPACK) than would be
      computed by directly measuring the residual error.
      
      This problem was ultimately discovered when the
      doc_map_iwave case broke.  Even though this broken residual
      code has been in SPINS since before it was
      version-controlled via GIT, the map_iwave case would still
      converge (and relatively quickly) when the multigrid
      iteration had a relatively large coarse-solve size.
      
      Git bisect pinned the broken documentation case on the
      change that reduced the coase-grid size, which reduced the
      GMRES convergence rates enough that the errors caused by
      *this* problem broke convergence.
      
      Since this change replaces the error norm calculations used
      by GMRES, it should be treated with caution and mapped-grid
      cases should have a mark-1-eyeball inspection of results for
      a while.
      
      --
      
      Additionally, for debugging utility this change also
      includes crude residual/basis output for the 2D GMRES
      solver.  All current uses are commented out.

      Make BPE_from_internal an optional argument · ba41b112
      David Deepwell authored
      Also reorganize how some diagnostics are added to the file.
      This is now a little clearer to read since similar diagnostics
      are placed near each other.

      Change order of compute_Background_PE optional arguments · edf41beb
      David Deepwell authored
      The dimensional rho option should not be after the mapping options
      since the mapping options will need to be specified for an
      unmapped dimensional density case. This now makes the optional
      argument ordering more logical.

      Small fixes for broken build · f69389d7
      Christopher Subich authored
      In the previous merge, compilation of Sorter.o went missing from the
      Makefile, and a typo was introduced in the gravity_current case file;
      each would prevent a build from finishing.  These are fixed.
