Dear Custommer Support,
I want to graph vector fields for my differential equations but sometimes Mathematica show the graph, sometimes it doesn't. When it doesn't, it display only ''GraphVectorField[........]. Is there a way to actually ''force'' the software to show the graph instead? I did try using Show function and I got an error message saying that ''BlaBlaBla is not a type of graphic...''
Here is an example of what I did:
P.S: The `PlotField` package loaded OK because I got 2 other vector fields graph OK.
