Hello
I want to ask if the simulation I did is correct?
in this case i simulate about the exterior ballistics of projectile using ansys fluent with Spalart-Allmaras model,
i want to get the aerodynamic coefficient of the projectile,
i had done with my simulation but i still confuse with it
this is some iteration graph of my simulation
please help me for my final project hehe

and can you explain what is the convergence?
