Okay so I have this vector plot, Yet I can't do anything with
it. The purpose of the vector plot is to measure the angle the
vector makes with some axis. Is there a way to measure the angle of
the vector?
There is a no way to measure the angle of the vector directly, but if you take the three stress components (which I assume that you are doing), then you could calculate the angle.
what are you trying to measure with this vector and in what situation? May be I can come up with another way?
