How to initialize an unsteady problem with a steady solution in Fluent? Should I change the model to transient once the steady solution is converged?

Hello,

You can run the model as a steady state simulation. Once you have your desired convergence, you can switch the model to transient. After doing this, you can then, without re-initializing, run your simulation using the steady converged solution as your initial values. 

Quick curious question - why are you running your simulation in this manner? Are you planning on changing the value of your boundary condition in your transient run?

Best Regards,

Thanks Karthik. Even, I'm doing it in the similar manner. I'm not changing the boundary conditions. I'm trying to get a better convergence and to check the variation in the solutions with and without the steady state initial values.
