Combustion mechanics

[czc-zju]

I use “python ${PELE_PHYSICS_HOME}/Support/Fuego/Mechanism/Models/useful_script/script_trans.py mechanism.inp tran.dat” to obtain a new mechanism, but always get an error: File "~/useful_script/script_trans.py", line 53, in tran_list.append(outlines[spec]), KeyError: '!' I hope someone can help me, thanks a lot.

Hi, if you are using a current version of PelePhysics, then what you are doing won't work. These are the current instructions on how to generate a mechanism in PelePhysics: https://amrex-combustion.github.io/PelePhysics/Ceptr.html#usage Let us know if that doesn't work for you.

I'm using an old version of PelePhysics. Yesterday's question was answered, but when I executed ./make-mechanism.sh, a new error: UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 36: ordinal not in range(128), I hope you can try. tran.dat.txt mechanism.inp.txt therm.dat.txt

I think something else is going on. You have some characters in those files which are not parse-able and need UTF-8/ See for example discussion here or here

You should check the encoding of these files.

here is very helpful to me, the header and .cpp file have been successfully generated, thank you very much!!!

I'm closing this issue as it seems to have been addressed. Thanks !
