Hi guys,

I have a question on the sequence of the components of grad(U). I defined an new variable "gradU" in my solver, and I also monitored the time-series of gradU, see below
in solver:
    volTensorField gradU
in controlDict:
        type            writeRegisteredObject;
        functionObjectLibs ("");
        outputControl   timeStep;
        outputInterval  1;
, gradU is a 9 components tensor, and I assumed that gradU should arrange in this sequence: dudx, dudy, dudz, dvdx, dvdy, dvdz, dwdx, dwdy, dwdz.

However, here is the question. When I check the output gradU components, the sequence is definitely not what was shown above. I have to identify which component is dudy or dudz, etc. for my post-processing, but I was really confused. Could you guys tell me what is the components of gradU for my case? Many thanks!
