hadesmajesty Member Edison Join Date: Mar 2009 Posts: 40 Rep Power: 17	I am simulating a flat plane boundary layer flow. I want to set the outflow boundary at infinity. I have tried to use the grid transformation methods of Roberts (1971), but it seems that the streching leads to instabilty in my code. So is there any good method to strech the domain to infinity? Thank you in advance.
