    302302||Rafael || '''in doubt''' || proposed the option 2 ||
     303
     304Other suggestion for the '''OPTIONS''' section is to tell the simulator to use the steady-state solution as initial condition for the dynamic simulation. In this case the NLP for the initialization is not necessary, because all derivatives are set to zero. A suggestion to set this option could be using the '''InitialFile''':

     306{{{
     307#!mso
     308FlowSheet Myflowsheet
     309    ...
     310    OPTIONS
     311     Dynamic = true;
     312     TimeEnd = 30;
     313     RelativeAccuracy = 1e-8;
     314     AbsoluteAccuracy = 1e-9;
     315     InitialFile = "steady"; # or InitialFile = steady, without quotes
     316end
     317}}}

     321||Rodolfo || '''agreed''' || will solve my problem with the gasifier that is not initializing, but the steady-state is working fine ||
