We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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
