[sympy] Electrodynamics in Physics Module

2014-02-10 Thread Rajath Shashidhara
Hello, I'm interested in implementing electrodynamics in sympy. Any thoughts about this? I don't seem to find any documentation about grad, divergence, and curl. Are they implemented? I'm willing to do this as well. Please give me feedback. Thanks. -- You received this message because you

Check out Sachin's work from last year. He has an electrodynamics module which is almost complete. Prasoon also has some branches with a vector calculus package which has the functions you are interested in, also with various coordinate systems. Both of these need work and improvements. Jason

Also, as I've mentioned elsewhere, we should modify limit to just return a Piecewise expression instead of raising this error. It comes up a lot (especially if you use symbolic coefficients), and I'd rather have a Piecewise answer than no answer. Aaron Meurer On Mon, Feb 10, 2014 at 7:49 AM,
