I have been trying to write a simple Python script that uses the Calculator
filter to take three scalars and produce a vector using the ParaView3.6
Python wrapping. This is trivial through the GUI Calculator Filter, but I am
having problems adding more than one scalar to the calculator object in my
script. From browsing the posts here and the C++ doxygen I've noticed the
use of AddScalarVariable and AddVectorVariable to accomplish this, but these
appear to be no longer available through the Python interface. Could someone
point out to me what I'm missing?
See below:
#-------------------------------------------------------------------------
from paraview.simple import *
connection = servermanager.Connect('localhost',11111)
er = servermanager.sources.EnSightreader(CaseFileName='/.../data.case')
er.PointArrays =
['x_velocity','1','y_velocity','1','z_velocity','1','cp','1']
er.UpdatePipeline()
calc1 = servermanager.filters.Calculator(Input=er,
ResultArrayName='Velocity')
calc1.ScalarVariable = ['x_velocity','x_velocity','0']
calc1.ScalarVariable = ['y_velocity','y_velocity','0'] #This overwrites
previous declaration
calc1.ScalarVariable = ['z_velocity','z_velocity','0'] #This overwrites
previous declaration
calc1.Function = '(x_velocity)*iHat + (y_velocity)*jHat + (z_velocity)*kHat'
#Produces an error... Variable does not exist
calc1.UpdatePipeline()
