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.

The y+ value depends on the geometry, velocity of the flow, viscosity and density of the fluid. Therefore, if any one of the factors is changing in your domain, then this change will be reflected on the y+ value also.
