im trying to calculate two variables (pressure and film thickness of air in an air-bearing) by solving a Reynold-equation using iteraion-loop. The problem is that whenever i change the iteration condition (e by Pn+1 - Pn < e ) i get a different answer which is by very little values of e not correct (and too high). That means that the result increases in inverse propotion to e. I have tried also using relaxation-factor but not a very big change happened.
any answer will be appreciated. tnx
