To simplify maintenance and further development of chemistry solution the
standardChemistryModel and TDACChemistryModel have been merged into the single
chemistryModel class. Now the TDAC mechanism reduction and tabulation
components can be individually selected or set to "none" or the corresponding
entries in the chemistryProperties dictionary omitted to switch them off thus
reproducing the behaviour of the standardChemistryModel.
For example the following chemistryProperties includes TDAC:
#includeEtc "caseDicts/solvers/chemistry/TDAC/chemistryProperties.cfg"
chemistryType
{
solver ode;
}
chemistry on;
initialChemicalTimeStep 1e-7;
odeCoeffs
{
solver seulex;
absTol 1e-8;
relTol 1e-1;
}
reduction
{
tolerance 1e-4;
}
tabulation
{
tolerance 3e-3;
}
#include "reactionsGRI"
and to run without TDAC the following is sufficient:
chemistryType
{
solver ode;
}
chemistry on;
initialChemicalTimeStep 1e-7;
odeCoeffs
{
solver seulex;
absTol 1e-8;
relTol 1e-1;
}
#include "reactionsGRI"
or the "reduction" and "tabulation" entries can be disabled explicitly:
#includeEtc "caseDicts/solvers/chemistry/TDAC/chemistryProperties.cfg"
chemistryType
{
solver ode;
}
chemistry on;
initialChemicalTimeStep 1e-7;
odeCoeffs
{
solver seulex;
absTol 1e-8;
relTol 1e-1;
}
reduction
{
method none;
tolerance 1e-4;
}
tabulation
{
method none;
tolerance 3e-3;
}
#include "reactionsGRI"
OpenFOAM Configuration
The main OpenFOAM settings are located in the parent etc/ directory. The bash and csh shells are supported and to configure OpenFOAM source etc/bashrc or etc/cshrc respectively which source the following files in the config.sh or config.csh respectively:
settings: core settingsaliases: aliases for interactive shellsunset: sourced to clear as many OpenFOAM environment settings as possiblempi: MPI communications library settingsensight: application settings for EnSightparaview: application settings for ParaViewscotch: application settings for compiling against scotchmetis: application settings for compiling against metis 5
The config.*/example directories contains various example configuration files for the corresponding shell:
compiler: an example of fine tuning ThirdParty compiler settingsopenmpi: an example of fine tuning openmpi settings for OpenFOAMparaview: an example of chaining to the standard config/paraview with a different ParaView_VERSIONprefs: an example of supplying alternative site-defined settings
