The geometry is a cylinder. Using the calculator I do rad =sqrt( x**2+y**2) I would like to extract the cylinder surface which is rad = 0.1 I click on threshold then information to see rad 0.1<rad<7 I click on extract and enter the values min = 0.1 and max 0.1 for rad I get this message w arning: In /home/utkarsh/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/ParaViewCore/ServerManager/Rendering/vtkSMPVRepresentationProxy.cxx, line 279
vtkSMPVRepresentationProxy (0x359fd080): Could not determine array range. Any ideas to the solution of my problem? Thanks in advance, Stephen
