[Paraview] Broken Streamlines

[Steytler, Louis Louw]

Hi Everyone,

Thanks very much for all the suggestions.

Setting the streamline interpolator type to:

streamTracer1.InterpolatorType = 'Interpolator with Cell Locator'

solved the problem!

Thanks  again,

Hi Louis,

Is there any chance this is the rendering precision issue called depth buffer fighting? What happens when you turn off display of the plane? Are the streamlines still broken?

Hi Everyone,

When generating streamlines from a 3D computation, in some parts, the streamlines appear broken. This is shown in the attached image (the arrows point to the broken parts).

Increasing the "Maximum Streamline Length" parameter did not help.

Using the "Point to Cell Data" filter, and then generating streamlines on the cell data did not help.

Although in the image shown the broken parts are in an area of low velocity, this happens in regions of high velocity as well. It also does not seem to depend on grid resolution, as the broken parts show up all over.

Has anyone experienced anything like this? Any ideas how to work around this?

Thanks very much,
