Hi all,
I am wondering about the similarities between the advection schemes "High Resolution" and "Second Order Upwind" in CFX and Fluent, respectively. As I understand it, the principles behind the schemes are the same; CFX: ![]() Fluent: ![]() In CFX, ![]() In the CFX documentation, it is decribed how ![]() ![]() ![]() Thanks in advance. Best regards, Reine |

I realized my mistake: the details of the limiter in Fluent are actually described in the documentation. It seems that the limiter used in the High Resolution scheme corresponds to the "Standard Limiter" for Second Order Upwind in Fluent; both are based on principles by Barth and Jespersen.

In CFX-Post, there are variables with names "-beta" that indicate the value of the limiter
![]() Does anyone know if there are corresponding variables available in Fluent, and what their names are? I have not found any variables that I think match. In the Fluent documentation, the scalar that limits the gradient is denoted ![]() |
