Some questions with boundary layer simulation #110

Hi:

Suppose you do a boundary simulation, the inflow Reynolds number Re= 450 based on the inflow displacement thickness δ. The computational domain is x * y z = 3000δ * 100δ * 120δ.
You made a mesh box with 3000 * 100 \ 120. Question: what is the value of L_free_stream ?

Best regards! Yue

It will depend on the actual mesh dimensions. These dimensions will be non-dimensional. Check out the examples here: https://github.com/HiFiLES/HiFiLES-solver/wiki/Non-dimensionalization

Let us know if you still have questions.
