Kiva - v0.6.3

Fixes:

  • Proper application of radiant temperature boundary conditions in the heat balance equations
  • Automatic detection/correction of floor polygon entry in the wrong direction
  • Prevent a potential divide-by-zero case for floors with no exposed perimeter and zero-flux deep-ground boundary conditions

Kiva - v0.6.2

Maintenance

  • Ensure compilation with C++17
  • Update dependencies to latest versions and utilize submodules to facilitate easier updates in the future
  • Migrate CI to GitHub Actions
  • Other CMake build process improvements

Kiva - v0.6.1

Fixes:

  • Fix issue where the top of interior insulation could be part of both the wall-top and slab boundaries.

Kiva - v0.6.0

Features:

  • Add Aggregators and Instances to libkiva. These are high level objects used for performing common functions when integrating Kiva into whole building simulation tools.
  • Add the ability to define callback functions for convection algorithms. This is useful when a program calling into libkiva has a variety of algorithms to choose from.
  • Boundary conditions now include the option of defining different convective temperatures for walls and slabs.

Fixes:

  • Fix typo in copying of MoWiTT convection correlations.
  • Fix issue where the top of exterior insulation could be part of both the wall-top and grade boundaries.

Kiva - Version 0.5.0

Features:

  • 10-25% speed improvements!
  • Changed to more permissive BSD 3-clause license.
  • Added better access to boundary conditions in libkiva, including:
    • mean radiant temperatures seen by the slab and interior walls
    • modifiable deep ground boundary temperature

Fixes:

  • Major refactoring of source code to eliminate redundancies in code.
  • Fix changing surface cell properties (e.g., emissivity) via the higher level
    Foundation inputs in libkiva.

Kiva - Version 0.4.0

Features:

  • 64bit Windows, Mac, and Linux versions.
  • Ability to define any block of material within the domain.
  • Add inputs to define the foundation footing.
  • Add ability to define exposed foundation perimeters (including unexposed/core
    foundations).
  • Make horizontal insulation depths relative to the slab and grade surfaces.
  • Replace foundation wall height ("Height") with depth relative to bottom
    of the slab ("Depth Below Slab").
  • Move boundary, initialization, numerical settings, and output related inputs
    to a higher level.
  • Switch to simpler linear solver (Eigen).
    Removes inputs for solver and preconditioner.
  • Separate core functionality into a linked libraries.
  • Use continuous integration for building and testing.

Fixes:

  • Improve output reporting. 2D simulations now report heat transfer rates
    representative of the 3D inputs.
  • Allow interior temperature file to be relative to input file (or in working
    directory).
  • Create output snapshots directory in same directory as the simulation output
    CSV file.
  • Small fixes to solar and convective boundary conditions.
  • Better error handling.
