Can this equation be solved with a partial differential equation package? It looks like an interesting non linear differential equation to which there may be an analytical solution. In order to eliminate the complexities of the spherical polar coordinate system I can set up the problem in the Cartesian system. In any case we have already proven the method of UFT356 and there is a great deal of interest in the latest UFT papers as you can see from this morning’s report. It would be interesting to model boundary conditions on an actual circuit such as that of UFT311, which is the ultimate aim of the research.
