Hello

In my CFD work, I perform cavity flow modeling. I carry out this work through both Fluent and Star CCM+.

Within the scope of this study, I run my analyzes in steady state. At the end of the analysis, I calculate the forces and moments in the x-y-z directions on a representative missile that I placed in the cavity. However, even though I used the same conditions and almost the same meshes in both software, my results are different. So much so that some forces have different directions. What could be the reason for this situation?

I can obtain experimental results in the transonic flow study around the RAE 2822 airfoil that I performed with both software. But I guess things change in cavity flow.. :/

thanks in advance...
