iteration automation

prakash

hi i am doing a simulation in my case i am giving the boundary conditions as constant values fluent will take up these values and uses them at the time of iterating once the solution get converges it stops . now my ques is , for the second time the boundary conditions are decreased by .1 and again manually we give iteration option this is done for five times . I just want to do this continoues iteration process for five different values like for example 5, 4.9, 4.8, 4.7, 4.6 , so what is the loop should be used to carry out iteration process continously five times and also what is the the macro to be used
