Electric field between two electrodes - Scilab

[baracoda]

Homework Statement

Calculate electric field between two electrodes - one square and one circular. Dimensions of the electrodes are given (diameter a and length of the square side b) as well as their potentials. The square electrode is placed inside the circular one. The student should identify the areas with the highest field value and present plots of the field intensity and of the potential. The accuracy of the solution must be verified. The solution should be performed for at least three different sizes of square grid.

Homework Equations

This is the task I have to do in Scilab. As I have absolutely nothing in common with Physics, please give me any hint. I would appreciate it. Please do not assume that something is obvious for me and explain as to a little kid :)

The Attempt at a Solution

After the research I think I should solve two Laplace equations (in polar and cartesian coordinates) and then sum the results, but I am not sure about that.

I will start with the basics:1) I should define the boundary conditions - the potentials of the electrodes. 2) I should create the meshes - divide the area into small cells. 3) Then I should solve the Laplace equation for each cell. 4) After that I should present the plots of field intensity and potential. 5) Finally, I should check the accuracy of my solution. Is that correct? Any other tips are welcome.
