delete vector at boundary

I Want to remove the vectors at boundaries. such as mentioned in the attached file
Is there somebody who can help me? I really appreciate any help you can provide.


If you mean that you want to remove vectors with zero velocity, you can use the Threshold filter to remove vectors with zero velocity. Here, the threshold filter targets scalar values, so if you do not have the magnitude of the velocity vector as a scalar value, you will need to create it, e.g. with a Calculator filter.
