Hello,
I have an unstructured dataset with a vector field defined on it (vorticity). I generated the gradient tensor and I know that the components are given as a tuple from 0 to 8 as dw1/dx, dw1/dy, dw1/dz, dw2/dx… dw3/dz. Now I need to compute the laplacian of that field, so I need the second derivatives; I used the gradient filter again and as expected I got 27 components. Does anybody know how they’re ordered?
Hi,
Did you find the solution to this question? I am currently trying to find the same thing, that is the convention of the second derivative output of the 27 outputs we get.
Please let me know if you are aware of it.
Hi,
No. In the end since I needed other things based on the laplacian I ended up using a Python calculator and let numpy handle the tensor math. Sorry for not knowing more.
