Dear Mathieu,

Thanks in advance for your support.

For the related data, please refer to this topic:

> Dear all, I imported my CGNS domain file. When I load the domain everything is defined as “one-block” (please refer to the attached Figure). I would like to split my domain patches, like the domain boundaries and my geometry boundaries. Do you know how can I achieve that? Many thanks in advance. Regards, Gabriele

I “played” with the advance setting and I changed the Interpolation Type with Cell Locator instead of point Locator.

Now the streamlines looks uniform and not trimmed, but I cannot confirm if that was actually the problem that I was facing. (please see the attached Figure).

Many thanks in adavance.
