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.
