Use the Cython module from the Python installation specified by
'python_cmd', rather than the Python installation that is running
SCons. This allows complilation of Cantera for Python versions that
aren't supported by SCons (e.g. Python 3.4).
When the nonreactant_orders option was enabled, specifying reactant orders for
species which were not present in the phase previously resulted in out-of-bounds
memory access.
Caused most Matlab flame simulations to fail, e.g. those using
CounterFlowDiffusionFlame.m or flame.m. Fixes regression introduced in c1067aa.
Fixes#554
In this example, a time-dependent mass flow rate function is used to inject a
specific fuel mass into a reactor. This is a more practical use case for this
capability than the fictitious hydrogen radical igniter used in combustor.py.
Discontinuities in heat capacity, in contrast to enthalpy and entropy, are less
of a problem and are not always indicative of problems with a mechanism. As
such, a looser tolerance on this quantity is reasonable.
This threshold eliminates warnings from the nDodecane_Reitz.cti input file included with Cantera.
Looser tolerances can lead to instabilities, especially in cases where negative
concentrations of charged species are found at the end of the first solving
stage.
Create a base class (IonFlameBase) for both IonFreeFlame and BurnerIonFlame, and
use the set_axisymmetric_flow() and set_free_flow() methods to select the flow
type.
Also combines FreeFlow and AxisymmetricStagnationFlow classes into class
IdealGasFlow.
Previously, calls to setTemperature, setDensity, and setState_TR did not result
in the underlying Substance object being updated. In addition, the
isothermalCompressibility and thermalExpansionCoeff methods did not synchronize
the state.
Now, setting the state of the PureFluidPhase object always sets the state of the
Substance object, and no synchronization is required in property calculation
functions.
The test for a sufficiently wide domain short circuits the normal control logic
which makes a call to refine() after each successful steady-state solve. This
caused failures for certain cases where sucessive solutions on wider grids with
only a few points still failed to satisfy the gradient criterion at the edges of
the domain.
Results in increase in mixture-averaged thermal conductivity of ~1% or less, and
a similar increase in laminar flame speeds, at least for some test cases.
Modifying Reaction and Species objects alone does not affect Kinetics or
ThermoPhase objects unless the modified objects are passed back to
modifyReaction or modifySpecies.
The check was being done at a stage where the token being checked could be just
a part of a key (if the key contained a colon), where this partial key could
correspond to another valid key.
Fixes#525
If Soret diffusion and mixture-averaged transport properties are
enabled, test that an exception is thrown. Also test that
multicomponent diffusion and Soret diffusion can be enabled/disabled
in either order. Also test that the automatic flame solver
correctly disables Soret diffusion.
The user can enable Soret (thermal) diffusion or multicomponent
transport in either order, but attempts to solve flame problems with
Soret enabled and the mixture-averaged transport approximation will
result in an error
