I have updated the PDE-separation branch again, it is now in 'pde-separate-v2'. In case you have sympy's sources already checked out: $ git remote add plaes git://github.com/plaes/sympy.git $ git checkout -b pde origin/pde-separate-v2 About API: I have two higher-level functions called: pde_

Hey Priit, I don't know anything about PDE's, but if separation of variables in pde's is anything like separation of variables in ODEs, then this function I wrote might be of use to you. Pull this branch: http://github.com/asmeurer/sympy/tree/odes and check out the separatevars function.
