 Details of FEMM's axisymmetric magnet formulation are something of a frequently asked question.  A page explaining the formulation and deriving the element matrices is now on the [[axisymmetricformulation|AxisymmetricFormulation]] page.

 To provide smooth estimates of torque and back EMF in a rotating electric machine, some sort of motion model is needed.  The [[slidingband|SlidingBand]] page describes the motion model used in FEMM, so that continual remeshing is not required for machine models with motion.  The approach is sort of a combination of previous "moving band" and "interpolation" approaches to this problem.

 In a **[[http://inds11.uni-klu.ac.at/lectures/Presentation%20ISTET.pdf|recent conference presentation]]**, the convergence of FEMM was compared to several other programs, including several solvers with various sorts of adaptive mesh refinement.  Some recent changes have been made to improve the convergence of FEMM by changes to the meshing.  While the program does not use adaptive meshing, several heuristics have been added to the mesh generation.  These changes result in convergence that is similar to programs with adaptive meshing on 1st order triangular elements.  [[http://www.femm.info/wiki/ImprovedConvergence|This note]] compares the performance of the scheme to various adaptive solvers on a specific electrostatic benchmark problem.

 **Wire Size Worksheet**
 A fairly widely used analytical formula for the diameter of bare wire as a function of AWG wire gauge is:
-  <html>d<sub>wire</sub></html> = (0.324861*inch)*exp(-0.115943*AWG)
+<html>d<sub>wire</sub></html> = (0.324861*inch)*exp(-0.115943*AWG)
 A Mathcad worksheet that implements this function (and a few other functions related to wire resistance and weight calculation) is linked below.
