I found the volume refinement is important on SPHVolumeInterpolation. And I can set it easily in GUI. But I can not find this in both the guide and script tracer.

Thus, I’d like to ask if there any functions in pvPyhon to set these parameters?  
Thanks

if “sPHVolumeInterpolator1” is your Python object in pvbatch/pvpython, then the resolution can be set like this:

sPHVolumeInterpolator1.Source.Resolution = [512,512,512]
