You should be able to write any single-element operation in a PythonCalculator filter.

I had to calculate the transpose of the velocity gradient tensor. I followed the following steps:

  1. First I calculated the gradient of the velocity using the Gradients of Unstructured DataSet filter. The Result Array Name was given as Gradient
  2. Then I applied the PythonCalculator filter. The code I entered was numpy.transpose(Gradient)

I got an error which says Could not find a suitable VTK type for object

Can you please tell where I have made a mistake and whether the steps I followed are correct?
