Hi,

I'm modeling a combustion chamber working on n-heptane + air mixture. When I try to initialise the solution I get the message "floating point exception" (for the cold flow computation). In the same time this case runs well with air instead of heptane.

Any suggestions will be appreciated ,

Julie

the possible causes are:

1. Your Boudary Conditions do not represent real physis.

2. Your mesh so heavy that your computers resources are not enough. try to use coarser mesh.

hope this will help.

u r welcome for further help

regards
