a.hajisharifi New Member Arash Join Date: Dec 2015 Location: vienna Posts: 15 Rep Power: 10	i have a big problem with paraview. first of all i attached my geometry.i would like to see stream tarcer in the boundary (plane yx).in the boundary there is Ux and Uy but Uz should be zero in order that if i put a stream tracer in a yx plane ,this tracer should not go out from this plane.but due to numerical error in simulation, there is some Uz (about 0.0000001) and it make my stream tracer go out from the plane. so my question is how can i force paraview to make Uz in this plane exactly 0 not 0.00001. i used calculator but it didn’t do this for me.\ please help me about it.\ thanks in advance Last edited by wyldckat; April 26, 2019 at 13:51.
