Der Ali is probably right, create a large circle around your structure as a boundary condition. It's been a couple years since I've used FEMM but I think that's it.

You have no materials set and no exterior boundary.. also you have 2 points in "nowhere" with no properties.. how do you expect the solver to solve this? Ok you have 2 conductors defined with 0V and 1V thats a start.. but how should it mesh or solve? shall it mesh to infinity or your screenboundary?
Look: the error you get is a perfect description of what your problem is --------------------------- femm --------------
------------- Material properties have not been defined for all block labels cannot analyze the problem --------------------------- OK ---------------------------
Soo.. first of all: define your blocks (conductors and air regions) Then set block labels in every! block And use usefull boundary conditions. ´ The solver is like a human.. you give not enough information it wont cooperate. Just think about if you were asked to draw an electrostatic field... the first thing you would cry out: "how much of it - it extents to infinity, oh i will die doing it!"

Here you go. ]electrodes.zip[/file] Its surely not what you want and i have set no outside boundary condition but it computes and gives you a colorfull image. Use it as a start.
