Dear friends,

I am simulating the "slightly compressible fluid" I am not sure which type of scheme, I must use, I found the details about both the explicit and implicit scheme. I am not sure, which I can use for the steady-state and unsteady state. In the user manual, it says to use low diffusion discretization must be used only for subsonic flows.  In Ansys 18.1 I have just two options like AUSM and ROE-FDS there is nothing like the "Low Diffusion ROE_FDS" scheme. any suggestion for choosing the solver parameter. ?

Hello,
I would suggest you to update Fluent to a newer version.
Please give us a overview on what you are looking to simulate - a problem description and an image is possible?
