using stored solution in a matlab loop

Dear all
I am simulating a multiphysics problem which combines electric current with heat transfer, for multiple pulses .
I am trying to use a stored solution as an initial value for the proceeding MATLAB loops in order to see temperature accumulation. Is there a new command for using a stored solution in COMSOL 4.4? . I know there is an available command in COMSOL 3.5 "asseminit", is there a replacing command ?
Thanks for your help
