Hi Lorenzo,
The code in the attached notebook uses DSolve
, the error you reported is from NDSolve
. Did you attach the right notebook? The error message I get is
DSolve::deqx: Supplied equations are not differential or integral
equations of the given functions.
DSolve[eqns, {x, y}, t]
The equations in eqns
do not depend on x
, y
, or t
. Need to use the functions and independent variables in eqns
as the arguments to DSolve
