But how do I know what is the correct boundary >dimension and step size to get the correct convergence result? One way is to do it twice, with different boundary dimensions and step sizes. If the results are significantly different, the larger values were too big. So you do it again with the smaller values and a pair of yet smaller values, and repeat until you get two sets of results that are little different. But there may be a more sophisticated way of deciding. Experience counts, too. -- OOO - Own Opinions Only.
