> Hello,
> I am using Paraview to visualize large 3D velocity field (uniform
> rectilinear grid) I want to draw 3D Isovalue (contour filter) of a
> component of the field.
> In paraview 3.10, I cannot  select the contour filter directly and I
> have to create with the calculator a new scalar field equal to the
> velocity component and then use the contour filter to visualize the 3D
> iso-value.
> As the data is large, the creation of this new field with the calculator
> is very slow, and it seems that the data is duplicate.
> Is it possible with paraview or using a python script to use the contour
> filter directly on a component of a velocity field.
