Hi,

I am completed a simulation of an impeller and I would like to produce a velocity vector plot:

1) How can I filter out the velocity vectors on the wall which are travelling in the opposite direction (because of wall shear/ velocity at wall being zero) and therefore affecting the the max velocity. I have seen a lot velocity vector plot on line and one of them show this.

2) I am trying to plot the velocity vector on a meridian surface. So far I have used the offset surface feature which does what I want but has gaps which makes sense because the offset feature is from the impeller hub which has the vanes/blades protruding. Essentially I want to produce a surface shaped as shown but has no gaps and acts as a plane, meaning takes a section of the domain rather than offsetting a mesh from the surface.
