Segregated Solver

Hello,

I was wondering if someone could perhaps explain to me the nature of the segregated solver so that I may understand it a little more clearly. I have seen other threads discussing this in the past yet I still have some questions. In particularly I was wondering if when using this solver is each segregated step solved in an iterative manner. For example I am solving a system which incorporates several different chemical species. The transport of each of these species is coupled with one another and also fluid transport which I have also modeled.

So I have species 1 whose production is dependent upon the concentration of species 2. The transport of species 2 is meanwhile dependent upon chemical species 3. And the transport and in particularly the production of species 3 is dependent upon species 1 and 2.

The way that I have things set up right now is using a segregated solver I choose the first step to solve for laminar flow
The second segregated step I have aligned with Chemical species 1 and the third step solves for both species 2 and 3.

Will Comsol automatically iterate this in the segregated solver until convergence?

Appreciate any clarity which one could provide. Also good examples dealing with 3d mass transport and fluid dynamics would be useful as well.

Thanks

Pat
