Achieving convergence in combustion simulations in ANSYS Fluent can be challenging, but with the right approach and understanding, you can improve the likelihood of obtaining converged results. Convergence is crucial to obtaining reliable and accurate simulations. Here are some tips to help you achieve convergence in your combustion modeling:

• Perform sensitivity analyses for critical parameters, such as reaction rates, turbulent kinetic energy, and dissipation rates, to understand their impact on convergence.

• ANSYS Fluent offers different initialization methods like Standard, Hybrid, and Segregated. Try using different initialization methods to see if it affects convergence.

• If you have access to combustion experts or relevant literature, consult them to get insights into your specific combustion model setup.

• If you are still facing convergence issues, start with a simpler model and gradually add complexity to isolate the source of the problem.

Remember that achieving convergence might require several iterations of tweaking and refining your model setup. Be patient and systematic in your approach, and keep track of the changes you make to understand their impact on convergence.
