[Contact the author for more details - moderator] Hi. I'm trying to solve system of differential equations from astrophysics. It appears that I have made some misterious mistake in mathematica code, but I have no idea where since all mathematica error messages are absolutely non-informative. Anybody can take a look ? P.S. I get the following errors: Possible spelling error: new symbol name "diffEqP" is similar to existing symbol "diffEqM". NDSolve::"ndnum": "The right-hand side of the differential equation does not evaluate to a \ number at r == 0.`.
