After setting the "language_level" directive (6c0866ef), nested comprehension
expressions erroneously triggered an error message from the Cython compiler
saying "local variable 's' referenced before assignment". While the problem has
been fixed in Cython 0.27 and newer, this commit restores compatibility with
older Cython versions as well.
This fixes the warnings generated by recent versions of Cython that
the language_level will be changed in the future. By setting this
directive, all the code in the .pyx files should be written in
Python 3 syntax. This required several changes to the import
syntax in the files to fix relative vs. absolute imports
ctml_writer was severely truncating Redlich-Kwong coefficients when converting
from CTI to XML formats, keeping only 5 significant digints in the "a"
coefficients and two decimal digits in the "b" coefficients, which is less than
what is used even in the example CTI files. The use of the "%f" format also
meant that the precision depended on input units.
Since the leading Chebyshev coefficient has effective units like
log(cm^3/kmol), it needs to be converted directly to the default units of
the CTI file.
Analogous to the fix for PLOG reactions in #435.
-Removes option to read tabulated thermo from an external csv file (this is now
handled from within cti or xml).
-Renames `rateCoeff` keyword to the more appropriate `rate_coeff_type`, and fixing
keyword order so that this new keyword is listed last.
-Removes `else` statement from `if isinstance(self._standardState, standardState)
-Removes unused `_pure` attribute from `IdealSolidSolution` and
`BinarySolutionTabulatedThermo`
-Changes default on `tabulated_species` keyword to `None`.
-Removing superfluous `standardState:_build` from ctml_writer.py
- Removes unnecessary conc_dim() definition in `table` class.
- Removes unnecessary units defintion for mole fractions in `table` class.
- Improves grammar in error message for case when thermo table is
not provided for `tabulated_species`.
The keyword `standardState` was added to species::__init__ in
ctml_writer.py. This moves this keyword entry to the end of the
list of keywords, so that species instances of the class do not
need to reorder their keyword order.
Update diffusion_flame_batch.py and diffusion_flame_extinction.py
to use CanteraError where appropriate. Define a new
FlameExtinguished exception to distinguish between extinction and
other failures. This allows things like OSErrors to still be
raised to the user while dealing with exceptions we can handle.
Closes#569.
Previously, lines which did not contain a reaction equation or a known keyword
and did not contain any slashes would be silently skipped. This caused reactions
mistakenly written using '->' as the arrow to be ignored without warning.
Fixes#583
When using the 'auto' solver option, user-provided arguments to
set_initial_guess were not being saved for subsequent calls to set_initial_guess
within Sim1D.solve, causing the solution to always be for equilibrated products.
This removes Python 2.7 support from the "full" Python module. The
"minimal" Python module (the ctml_writer and ck2cti scripts) and the
SCons build system still support Python 2.7.
Remove 'from __future__' imports, specification of base class
'object', and arguments to 'super()'.
Make use of 'str' being the unicode string type.
Eliminate special cases which require checking the version.
Fix some deprecation warnings issued by legacy capabilities.
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
