Opening Cantera .cti file

[Erik Howard]

I ran the "Gasonline Combution (Cantera).dwxmz" sample and recieved the following error:

Combustion (Cantera): CanteraError:

CanteraError thrown by ct2ctml_string:

I tried to troubleshoot the initial part of the python script from the model outside of DWSIM without success as the "system" module is not recognized outside of Ironpython (as best as I can figure).

*** Script Exerpt *****
import cantera as ct
import System
from System import IO

ct.add_directory(IO.Path.GetDirectoryName(Flowsheet.FilePath))

gas1 = ct.Solution('ChemDetailed.cti')

I can run the initial part of the script however outside of DWSIM by specifying the direct path to the Chemdetailed.cti file, so I am comfortable that Cantera is functioning properly.

**** Modified Script ***
import cantera as ct

gas1 = ct.Solution('direct/path/to/CTI/file')

I have python Anaconda 2.7 installed on my machine. Is it necessary to have ironpython installed?

Thanks in advance,

Hi Erik,

ctml_writer.convert(r'C:\Users|KnightHawk\AppData\Local\DWSIM5\samples/ChemDetailed.cti',outName='STDOUT')

Try modifying the script to change the slash after 'samples' to a backslash.
