I Alan sorry but i dont know how to solve your problem. I write only because i understand your sense of frustration! Im absolutely sure that the differential equation you are trying to ndsolve is solvable in terms of some type of special function (maybe Kummer functions) but, as you say, NDSolve is not able to solve it and i dont understand why because sometimes this package is able to solve very more complicated equations! This make me very unhappy... ----- Nicola Attico (attico at cibs.sns.it)
