How to plot streamline on 2D velocity contour?

Hi thanks for the quick reply. I tried but I get the following error:

ERROR: In C:\bbd\8fbebceb\build\superbuild\paraview\src\VTK\Filters\FlowPaths\vtkEvenlySpacedStreamlines2D.cxx, line 125
vtkEvenlySpacedStreamlines2D (0000017C53E8E7A0): vtkEvenlySpacedStreamlines2D does not support planes not aligned with XY.

Respective if I use it on z-plane:

ERROR: In C:\bbd\8fbebceb\build\superbuild\paraview\src\VTK\Common\ExecutionModel\vtkExecutive.cxx, line 753 vtkCompositeDataPipeline (0000017AB5754D50): Algorithm vtkPVGeometryFilter(0000017BA0098320) returned failure for request: vtkInformation (0000017AE9B67870) Debug: Off Modified Time: 50048809 Reference Count: 1 Registered Events: (none) Request: REQUEST_DATA_OBJECT FORWARD_DIRECTION: 0 ALGORITHM_AFTER_FORWARD: 1 FROM_OUTPUT_PORT: 0

My workflow for is so far:
-slice vertical or horizontal plane

  • claculate with Calculator : U_XiHat + U_YjHat
  • apply EvenlySpacedStreamlines2D

Do I need to do something else?
