Hello,

I am working with a cfd vtk dataset which has a number of scalars (chemical species concentrations for instance).

I need to be able to arrange them into an array, like a python list for example, and compute the minimum or maximum values. For example, I need to find the most common species at each domain point. It sounds pretty straightforward but I was unable to do so with either calculator or python calculator.

If for example I try to create a list of the scalars it tells me the scalars don’t exist. But if I try to store the a single scalar I have no issues.

Any help here is appreciated.

Thanks,
