Hello, I am new to using FEMM and to electro magnetism - I'm a mechanical
engineer fresh out of Univ. or Washington! I have a new job and I'm
jumping right into this stuff. I'm looking at modeling the field that
results from a magnetric flow meter. I am pretty much following example
2 from the FEMM website; however the example shows a transverse slice of the
inductor and I want to model a axial slice so I am confused about how to do
this. I attached my current FEMM file.
basicallly I have a simple inductor and I want to know what the mag lines
look like. I setup the geometry, meshed it, applied material properties,
and a boundary condition and ran the solution. the results don't look
right. My confusion is that the flux lines should parrallel the inductor, but
instead they radiate from the inductor ( in a circular fashion with the
inductor at the center). so how does FEMM know how my coils are oriented? From
the results it looks as thought FEMM thinks I have a transverse slice of my
inductor, however what I want to model is an axial slice.
Can anyone offer some advice? thanks!
