From: Chem IITKGP Chaudhary on 17 Nov 2009 13:18 hi i am trying to solve a set of 7 coupled second order ode's in spherical coordinates. i went through the tutorials for solving ode's, but they are all in cartesian coordinates. how to solve them in spherical coordinates?? the seven equations are nothing but diffusion equations with source/sink terms . Each of the source terms is a function of the seven concentrations. plz help

The treatment of spherical coordinates is possible by setting m=2 in the formal problem description. Best wishes Torsten. |
