What is relation of L_free_stream and length in mesh? #109

Closed popstar0426 closed 8 years ago

popstar0426 commented 8 years ago

Hi: I understand that L_free_stream is Reference length corresponding to the chosen Re. The example is very clear: chord length of airfoil. However I have a question with the mesh generation? For example: I generate a mesh around an airfoil with chold length =1. Then I should set the L_free_stream to 1. Yes, no problem. But if I generate an airfoil with chold length =0.2, which value should I set for the L_free_stream?

Best regards! Yue

The discussion on non-dimensionalizaton in the documents addresses this question directly. Please let us know if it is not clear. On Thu, Oct 29, 2015 at 2:34 AM popstar0426 notifications@github.com wrote:
