TKI generation issue

filipimfs · December 17, 2019, 08:34

Hello all,

I'm trying to generate a TKI for a dual fuel combustion. I followed the Converge's User Guide (fig. 23.116) that shows that is possible to generate diferent types of mixture:

species_control:
custom_species_flag: 1
fuel_species:
CH4: [0.7000000, 0.5000000]
CO2: [0.3000000, 0.5000000]
oxidizer_species:
O2: [0.2, 0.5000000]
N2: [0.77, 0.5000000]

However, when I try to do this I got this error message:
FATAL_ERROR: More than one oxidizer mixture is not allowed

Is that a bug or is the user guide wrong?

Thank you,

Filipi

Hi -
Please compare your setup to the example you can load in CONVERGE Studio.

I think you need to set that custom species flag to 0.

Try and let me know how it goes.

Yes, I did compare with the tutorial.
I also changed the flag that you have mentioned to 0 and it is still not accepting multiple oxidiser composition.

Any ideia?

Thank you,
Filipi

Please upload your input files so I can try it here.

What version of CONVERGE Studio are you using, and are you using Windows or Linux?

I'm using the v3.0 from Nov, 20th on Linux.
The files are attached.

For the TKI table function, the user can only use one oxidizer composition.
