I understand that NDSolve will solve a set of first order coupled. diff.eqn. Here is my problem: I have a set of 20+ equation that all have the exact same structure and I can't seem to find an easy way to input them. For any help I'd be highly appreciative. The equations are of the form d V_k(l)/d l = V_k(l) + Sum[ V_k'(l), (k not equal k')] where k is the number of diff. eqn. Thanks for any help, Cyrill
