Hi Robin, here is the help text of the StoppingTest option In:= ?StoppingTest "StoppingTest is an option for NDSolve that can be used to stop the \ integration of the ode when a certain condition is found to be True. The \ condition can evaluate to True/False only and should contain the dependent \ and independent variables explicitly. This option cannot be used for linear \ boundary value problems." The result of NDSolve can still be used to obtain the results. Hope that helps Jens -----Original Message----- From: Robin Redfield <RedfieldRC.Dfem at usafa.af.mil> To: mathgroup at smc.vnet.net Subject: [mg14020] [mg13948] Options to exit NDSOLVE? >> >> >> Is it possible to get NDSOLVE to exit before the independent variable >> reaches its range?
