I'm doing some fluid flow visualizations, and I'm trying to compute the lambda_2 scalar field (which is the second eigenvalue of a tensor based on the velocity gradient). It seems like the python calculator has NEARLY everything I need (eigenvalue, gradient) but I also need to be able to take the transpose of the gradient tensor to get the symmetric and skew-symmetric parts. I can't find it anywhere in the documentation but there must be a transpose function, right?
If not - or if I'm approaching this wrong - how else can I compute the lambda_2 value from the velocity field? Thanks! *Gabe*
