Minimum set based on a regression in NumPy 1.8.0 which affects the SolutionArray
class.
This makes Trusty Tahr (14.04) the oldest supported version of Ubuntu (using the
Ubuntu-provided NumPy package).
Resolves#445.
Returning the special value ENTROPY298_UNKNOWN is (apparently) the expected
behavior if no actual value was provided, and should not result in an exception.
Also eliminates undefined behavior associated with unchecked cast to
LatticePhase*, since, at least in the Li7Si3_ls.xml example file, the
sub-lattices can be represented as other ThermoPhase types,
e.g. StoichSubstance.
This changes the order in which tokens are identified to be strictly
descending in length, so that third bodies are identified correctly
even when the third body expression could potentially be interpreted
as containing a standalone species name.
Reactions of the type
A (+B) <=> C (+B)
ought to work, as long as they are provided a pressure-dependent rate
expression. This commit adds three examples to the test file. The first
works OK, the second two cause problems.
(For what it's worth, this currently crashes the official chemkin.
Or at least the parentheses do; I've not tested the plus.
Ansys have created a defect record and say they will fix the issue.)
If geometry flags are specified rather that can't be cast to integers,
intercept the ValueError raised by Python and raise a more sensible
exception.
Fixes#446
The CounterFlowDiffusionFlame (CFDF) code is able to perform more general cases
of npflame_init for multiple species fuel and oxidizer streams. The
stoichiometric mixture fraction in the CFDF code uses the Bilger definition of
mixture fraction, using the conservation of elements C, H, and O. This method is
used in the python module, but not the MATLAB npflame_init function.
Also, the CFDF code uses the fuel stream density to calculate the fuel stream
velocity and the oxidizer stream density to calculate the oxidizer stream
velocity, where as the npflame_init code uses the fuel density for both velocity
calculations.
The elementMassFraction code is a MATLAB version of the python function:
elemental_mass_fraction, which is needed to run the CFDF code.
Update the diffflame.m example to use the more general CFDF function since the
input parameters are different than the npflame_init function. This example is
the same as the diffusion_flame.py sample in the Python module.
This fixes some platform-specific test failures when compiling in debug mode,
where estimated temperatures during the Newton iterations were too high,
resulting in non-finite reaction rates.
A very small change that allows the user to set the initial location of the flame. The original hard-coded values for "locs" are retained as the default, but the user can now modify locs.
