Hi Dave,

I think that the deformation tensor Dij is defined for compatibility with the definition of gamma.

In CFX Theory Manual: gamma = [2*(delUi/delXj : Dij)]^0.5 = [2*(Dij : Dij)]^0.5

In...

Hi, Dave.
Using tensor, you can easily prove that:
gamma = [2*(delUi/delXj : Dij)]^0.5

is SAME as
gamma = [2*(Dij : Dij)]^0.5

Therefore, for CFX
We can write:
sstrnr=gamma = [2*(Dij :...
