=============
Hello,
I'm trying to show a circle in a vector field in R^3.
Here's my vector field:
vectorfield01 = VectorPlot3D[{y, -x, 0}, {x, -2, 2}, {y, -2, 2}, {z,
-2, 2},
VectorScale -> 0.1,
VectorPoints -> {9, 9, 5}]
Here's my circle:
circle01 = ParametricPlot3D[{Cos[t], Sin[t], 2}, {t, 0, 2 \[Pi]},
PlotStyle -> Directive[Thick, Black],
PlotRange -> {{-2, 2}, {-2, 2}, {-2, 2}}]
Each of these individually gives me what I want, but when I try
Show[circle01, vectorfield01]
I get the error message
Show::gcomb: Could not combine the graphics objects in Show[\!\(\*
I've tried all kinds of combinations with Graphics3D[ ] etc.
Any help would be appreciated!
Thanks very much,
