We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello,

Please check the mesh (quality, refinement and aspect ratio) and the case setup (BCs, models and other necessary settings). Here is the tutorial which may give you a better insight for your application. This issue may also occur if the reference values are not set properly, since reference values are used to determine lift and drag coefficients.
