Hi,

 

Both single and double precision option is available for EDC model in Fluent. You can choose either or these solver types. If you use double precision, it will reduce the round off error . I would recommend using double precision for combustion simulations.

 

Please go through the section 4.1.2.2. Single-Precision and Double-Precision Solvers in 4.1. Starting Ansys Fluent
