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.

In my experience the nodes do not need to match, however the solver does require the distance between the fluid and solid mesh nodes to be < 0.25*(min element size of entire model). More details for this can be found in the LSTC ICFD theory manual you can easily find online.
