6. Basic User Manual Maxwell 2D Student Version Rick Hoadley Jan 2005 Overview e Maxwell 2D is a program that can be used to visualize magnetic fields and predict magnetic forces e Magnetic circuits are difficult to design because the materials used are non linear and the fields can not be confined like electrons within wires e This program makes the design process much easier steps 1 4 These are the eight steps in designing and analyzing a magnetic circuit 1 Open a project set up the file name and type of problem 2 Define the model draw the items in the circuit 3 Setup the materials specify what each item is made of 4 Setup boundaries and sources specify what happens outside the window you are looking at and specify any currents that are flowing within any item 9 6 Steps 5 7 Setup executive parameters are there forces or torques you want to have calculated Setup solution options determine how accurate you need your answers because the solution is iterative in order to get closer and closer to the final answer Solve the problem uses automatic meshing and finite element analysis to solve the problem steps 8 9 8 Post Process look at the solution to the problem This can be a plot of any of the following Flux lines Magnitude or vector of B Magnitude or vector of H Magnitude or vector of J Energy Torque Force etc 9 Exit Maxwell
