Hello, I am replicating a simulation of a fluent turbine in CFX. My idea is to check the drag, moment and lift coefficients. I know that the ones I got in Fluent are close to what I want to do but when I make the same simulation using the sliding mesh method in CFX, I get completely different data. The simulation is running fine but I don't know what may be affecting the data so dramatically. I wanted to see in the Post processing that it also allows calculating the expression in a certain Time Step and comparing the values ​​with what the CFX monitors show are different, something that seems strange to me if the two are calculating according to the solution made by CFX . Any recommendation?

PS: I am using exactly the same turbulence model and solution method. It also exports the mesh that I used in fluent, as in its 2D modeling, the program added a thickness and added the condition of symmetry between faces.
