Use with <A HREF="../DA/DMMGSetInitialGuess.html#DMMGSetInitialGuess">DMMGSetInitialGuess</A>() to use the current value in the solution vector (obtainable with <A HREF="../DA/DMMGGetx.html#DMMGGetx">DMMGGetx</A>()) as the initial guess. Otherwise for linear problems zero is used for the initial guess (unless grid sequencing is used). For nonlinear problems this is not needed; it always uses the previous solution as the initial guess.
