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"

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
