Modelling different time scale processes
Posted Oct 11, 2012, 2:18 PM EDT Version 4.2a 0 Replies
I dont want to introduce the equilibrium condition togheter with migration cause I would nedd to introduce a great reaction rate and possibly use a small time step, whereas migration is a slow process.
I have read topics in this forum about reaction equilibrium questions that was not answered.
I know how to implement segregated solver and multistep solution procedure but still can't find the way or have encountered in the internet an example of how to do what I want, Im pretty desperated.
Any help of how to introduce water equilibrium in my simulation??
Also I have read about add a algebraic constraint to the concentrations, but Im not totally sure that this really captures the schtochiometry of the water equilibrium
