Hi
I'm writing a python script that uses several paraview filters. I then extract
data from the final filter for further analysis in python. However, I'm having
a problem with the speed of the data extraction (can take several minutes). I
have tried writing to a file (createwriter) and then reading the file. I have
also tried servermanager.Fetch() and GetPoints… Although I am able to get data
with both methods, they are both very slow. I was wondering if there was
anything obvious in my paraview/python script that was slowing the process or
if anyone has a suggestion at how I may speed things up.
(I realise this could just be down to the size of my initial input, for small
data files Mesh - 15MB, solution - 50MB).
The script is below. Any suggestions would be greatly appreciated.
Regards
Christian
TBR = TAUMeshReader( FileName=Dir+'Mesh' )
TBR.SurfaceMeshOnly = 0
TBR.SolutionFileName = Dir+'solution'
MB = MergeBlocks(Input = TBR)
T1 = Transform(Input = MB)
T1.Transform.Rotate = [-float(Rot/2.0), 0.0, Sweep]
ISO = IsoVolume(Input = T1)
ISO.ThresholdRange = [MIN_Tot_Pre, BLE_Tot_Pre]
ISO.InputScalars = ['POINTS','total_pressure']
SL = Slice(Input = T1)
SL.SliceType="Plane"
SL.SliceOffsetValues = n
SL.SliceType.Origin = Inboard
SL.SliceType.Normal = Normal
Con = Contour(Input = SL)
Con.PointMergeMethod = "Uniform Binning"
Con.ContourBy = ['POINTS', 'total_pressure']
Con.Isosurfaces = [BLE_Tot_Pre]
Pass = PassArrays(Con)
Pass.PointDataArrays = ['wall_distance']
h=CreateWriter(Dir+'Edge.csv',Pass)
h.FieldAssociation = "Points"
h.Precision = 15
h.UpdatePipeline()
….read Edge.csv file for further analysis
