Hi all，

I have two different methane surface mechanism files. when I open them with notepad, one is well-organized and the other is disordered. however, they have the same suffix 'inp' and exactly the same content.

Both the two files can be imported into Fluent without any mistake. However, when I calculate, error occurs with the well-organized file like 'received a fatal signal (segmentation fault)'. Reasonable results can be obtained with the disordered mechanism file.

My question is what is the difference of these two files or how can I generate the disordered mechanism file with which calculation can be proceeded.

thanks
