      Add system file for the new belize3 · d63d8368
      Christopher Subich authored
      This adds belize3.sh, a system file for the newly-built belize3, using
      the g++ compiler.
      As a usage note, blitz requires python to build successfully.  As of
      this writing, python is only available on belize3 with `module load

      Update dependencies to Blitz 1.0.2 and update to new MPI standard · 937c04ae
      Christopher Subich authored
      This commit updates make_deps.sh to build newer versions of Blitz (1.0)
      and fftw (3.3.9).  The 2010 version of Blitz no longer builds with the
      newest versions of GCC, and there is no harm in updating FFTW.
      The newest versions of Blitz (github head) require cmake to
      build, and some systems still in use have old, incompatible versions of
      cmake.  Blitz 1.0.2 requires python to complete its build process (some
      files are auto-generated).
      The new version of Blitz dropped the blitz::Vector type, being
      equivalent to a 1-dimensional array, so it was replaced with
      blitz::Array<type,1> instead.
      Additionally, the Parformer (parallel transpose) code was adjusted to no
      longer use MPI_UB to define the upper bound of the array section
      datatype.  MPI_UB was deprecated in the MPI-2 standard and removed in
      the MPI-3 standard, so SPINS could fail to build with some new MPI
      libraries (OpenMPI 4.0.3 is confirmed to break).
      Because this commit updates dependencies, the patch version is

      wave_reader: compute hill properly with z-decreasing · 4fba6227
      Christopher Subich authored
      Previously, wave_reader computed the hill height as a fixed
        zgrid(:,1,1) - MinZ // matlab notation
      which implicitly assumes that z increases along the third index.  If
      that assumption is violated, the BPE calculation breaks (in ways that
      can cause assertion failures based on roundoff error, at that).
      Fixing the calculation as min(zgrid(i,1,:)) at initialization time
      alleviates this problem.

      wave_reader: allow FULL input types · 471ccd94
      Christopher Subich authored
      Previously, wave_reader locked 'FULL' (3D) input behind enabling
      restart.  This restriction was unnecessary, and doing so in fact made
      the specification of u/v/w/rho filenames useless.
      Deleting this check allows proper read-in of FULL datatypes, without
      faking a restart.  The only functional difference is that if
      perturbations are also enabled, they will be applied on top of the 3D
      data read.  This seems to be desirable, since it makes the application
      of the config-file settings more straightforward.

      Updates to solver parameters · 79b17389
      Christopher Subich authored
      Based on experience with a poorly-converging, steep hill case, the
      number of inner iterations in GMRES is increased to 40, and the number
      of outer iterations drops to 2.
      Please pay attention to GMRES warnings and report cases where things
      don't work well, there's probably an optimal parameter range (or else we
      could make the parameters a runtime config option).

      Fix topography error in wave_reader · 645e99d8
      David Deepwell authored
      The quadrature weights were found to be incorrect for mapped grids
      because they were adjusted using the topography which was not
      scaled properly. The topography needed to be adjusted to be relative
      of the 'minimum z-value'. This is in quation marks because it is
      not necessarily the absolute minimum, but rather the reference
      This shift also fixed the BPE calculation to have the same reference
      as the PE calculation.

      Fix error in tracer/rho safety dump in wave_reader · e5bec6c2
      David Deepwell authored
      The previous "fix" swapped rho and tracer.

      Add vortex stretching and enstrophy stretching production terms · a63ba535
      David Deepwell authored
      Vortex stretching is one of the dominant terms in both the
      vorticity equation and enstrophy equation. They also help in
      understanding the vortex dynamics and how energy at large scales
      cascades into small scales.
      The three components of vortex stretching (omega dot grad) u
      and the enstrophy stretching production (omega_i omega_j S_ij)
      are now included and can be computed with the derivatives
      case file. Files for vortex stretching terms are called
      vort-stretch<dim> where <dim> is one of x,y,z. The enstrophy
      stretching production file is called enst-stretch.
      As these quantities are the product of velocity gradients, care
      must be made to ensure adequate resolution is present.
      Update version to 2.0.3
