Setting COMSOL Initial Conditions from Matlab

Hello All,
I am looking to run a comsol model for a given period of time and then transfer the comsol results into a matlab program. These conditions will be modified inside of matlab and will then be sent back to comsol as the new initial conditions. Comsol will then run for another period of time and will once again transfer its results back to matlab for modification and so on and so forth.
In short I'm trying to write an algorithm that alternates between comsol and matlab using the final conditions of one to set the initial conditions of another.
I am very familiar with matlab and am relatively new to comsol. So far I'm having difficulty setting the instantaneous initial conditions inside of comsol for each point in the mesh(especially from a script). I'm also not sure how to resolve the indices of the results vector into physical locations within the mesh.
Any help would be greatly appreciated,
Josh

Hi
not been that far at that moment but this definitively on my "to do list" within the next 2-3 months [ have a look at the thread I initiated today regarding improvement on 4.1. it is related to that problem at least from my perspective [ changing geometry in matlab and resending "updated" conditions/initial solution to comsol .. back and forth...
"
I will be reading what will be posted here with great interrested and might have something to share in a not so far future
In my opinion, the api and livelink documentaiton are a MUST READ before embarking in such a project
