I’m trying to access the coordinates from a hierarchical box data set (AMReX) to do a computation.
What I really want to do is manipulate the coordinates since we are playing around with adding mesh stretching into our CFD code, but the underlying vtkDataType only uses
vtkUniformGrids. Or at least that is what it seems to me. After a bunch of trial and error with Programmable filters, I decided to just compute the stretched coordinates and use the
Warp By Vector filter.
With the regular calculator I can access them just fine with the
coordsX,Y,Z variables, but when I try to use the python calculator I can’t figure out how to access them at all. There is no
inputs.Points member, or at least calling it doesn’t do anything, and the fields don’t exist in the
PointData. Any advice here? Is this just not exposed via the python interface?
