Sorry if it's hard to read as I'm translating.

Hello everyone,

I am beginner at OpenFoam.
I would like to use chemkinToFoam to change the file to OpenFoam format and run the simulation.
My first error:I get this error over 100 lines, I solved it by +0.0007H to the right side.This file did not have this error when I calculated it with cantera.

--> FOAM FATAL ERROR:
Elemental imbalance of 0.0007 in H in reaction
reaction "C10H7CH2 + C6H5CH2C6H5 + 0.0009C = 0.06667BIN1B + 1.083375BIN1A + CH3";
A 2.98141e+09;
beta 0;
Ta 11573.4;



My second error:When I run reactingFoam with the OpenFoam format file created by the above method, I get the following error message.I replaced it with a file created by GRIMech and ran reactingFoam and there were no errors.

I would like to know how to use 'imblanceTorelance' as a tolerance setting and why a file that has been successfully chemkinToFoam dumps core.
