Definition of S in SpalartAllmarasDDES::rd
 

Hi,

in SpalartAllmarasDDES the denominator of rd uses the magnitude of vorticity, like the RAS-model. In the original paper Spalart uses the magnitude of the gradient of U, "in order to be slightly more robust in irrotational regions".

Hi Luise
 

Thanks.

rd has been updated and pushed to 1.7.x version on our web page.
