Maximum Pre-Exponential Factor?
 

Hi all,

I'm trying to incorporate chemistry into CFD solver. Currently, I'm using 64-bits FLUENT and running my case on 3ddp (3-dimensional double precision) version. However, once I increased pre-exponential factor of the reactions to 1e+38 or more, it stated that there is floating point error and overflow in cells. Is it true that the Pre-Exponential Factor is limited to 1e+038 or less? If yes, can please advise that is there any mean to address this problem?

Many thanks in advance.

Carl.
