Where can I call vtkPyFRAdaptor code?

[lj-cug]

Dear Sir:
I have read PyFR-Catalyst code throughfully, and don't know where to call the vtkPyFRAdaptor code. The question is I cannot find the PyFR driver code (in Server).
Is PyFRData.cu the driver code to generate live data? Maybe the code is still in development? I guess the adaptor code (vtkPyFRAdaptor) should be called in PyFRData.cu, then the data can be transferred into pipeline through Catalyst.
Wish you can give me some guides to how to use PyFR-Catalyst. Could you please introduce the basic workflow of PyFR-Catalyst using VTK-m?
Much Thanks!
