Please check the outflow boundary conditions: - YMC 28/07/06
- If possible, use other boundary conditions.
- Also, use a longer domain size in the streamwise direction and compare them with the original results. If the results with a larger domain do not have the negative velocity region at the same location (?<x<?, 5<y<10), then it means the negative velocity was the result of the outflow boundary conditions.
