CFD Online Discussion Forums - [General] get Bounds from different Mesh Regions

Dear all,

I would like to write a script in python. Therefore I need some Bounds of different Meshregions. I'm able to get the bounds from the internal mesh, but not from other mesh regions. I think the problem is, that I have to change the active Soure. But how is this possible? The code I tried is here:

Code:

#### import the simple module from the paraview

from paraview.simple import *

#### disable automatic camera reset on 'Show'

paraview.simple._DisableFirstRenderCameraReset()



# get active source.

resultsfoam = GetActiveSource()



resultsfoam.MeshRegions = []



# Properties modified on resultsfoam

resultsfoam.MeshRegions = ['BLADES']



(x1min,x1max,y1min,y1max,z1min,z1max) = GetActiveSource().GetDataInformation().GetBounds()

print (z1max)



resultsfoam = GetActiveSource()

# Properties modified on resultsfoam

resultsfoam.MeshRegions = []



# Properties modified on resultsfoam

resultsfoam.MeshRegions = ['INFLOW']

resultsfoam = GetActiveSource()



(xmin,xmax,ymin,ymax,zmin,zmax) = GetActiveSource().GetDataInformation().GetBounds()

print (zmax)

Thank you for your help,
Jonathan
