#Flow123d version 1.8.0
(2014-03-31)

User interface:

  • every equation can output any input, computed, or post-processed field, new keys: 'output_stream', 'output_fields'
  • input fields given in one list under key 'input_fields' instead of separated 'bulk_data' and 'bc_data' lists
  • improved mass balance files (yet not correct with reaction term)
  • output of discontinuous linear finite elements
  • enhancements in flow123d.sh script; changed syntax, support for MetaCentrum clusters
  • support for BDDCML parallel solver in Darcy flow model
  • relative references in the input file produce warning reporting used absolute path
  • input interface warnings for unknown keys in the input file
  • warning for usage of field default values
  • Flow123d tries to keep IDs of nodes and elements in output into GMSH format same as in the input mesh; but it is not guaranteed to future and/or for parallel case

Physics:

  • transition coefficients in coupling of different dimensions are computed from other parameters, 'sigma' parameter is additional scaling coefficient with default value 1.0
  • concentration sources in Transport DG
  • general reaction term for operator splitting; can combine dual porosity, adsorption and reactions
  • limited solubility model in adsorptions
  • TransportDG supports second and third order finite elements
  • TransportDG supports Dirichlet, Neumman, and Robin boundary conditions
  • Darcy flow supports non-compatible 2d-1d meshes
  • support for heat transfer simulations (based on TransportDG); can not be combined with solute transport yet
  • ConvectionTransport adapt its time step to match change times of the input fields

Internals:

  • transition to git, github
  • transition to ci2 test server; YAML description of tests
  • new output subsystem
  • Fields can read from input independently and can hold short time history
  • optimization of mesh reading
  • optimization of Schur complement computation
  • optimization of TransportDG assembly
  • fast interpolation method for nonlinear adsorptions
  • output of the input type tree in machine readable JSON format
  • use C++11; g++ 4.7 and newer
  • transition to petsc 3.4.3
  • run_test.sh script use flow123d.sh consistently, can be used also on parallel systems
  • general classes for interpolation tables (not used yet)
  • AdHocAbstractRecord - abstract record with different kind of documentation
  • automatic installation of BDDCML library
  • reimplemented BIHTree, faster and more robust
  • transition to gtest 1.7.0
  • automatic night packages for both Linux and Windows
  • replace EqDataBase by more general class FieldSet
