Hello there,
I am new to Unsteady problem in fluent. I am working on a Spray modeling in combustion chamber. I am running my simulation with Non premixed combustion with continuous fluid as air and the spray as diesel. Total simulation is for 0.050 seconds and spray starts at 0.002 s and stops at 0.045 s. The time step size is 0.0001 s and number of time steps are 500.
For this simulation please let me know, how can I decide the maximum iteration per time step ? How can I know that my simulation gets converged within the specified time steps ?
Any help will be highly appreciated. Thank you so much in advance.
