zero stress tensor -- CFD Online Discussion Forums

mottle New Member Join Date: Aug 2009 Posts: 13 Rep Power: 17	Dear Fluent Users! I faced with following problem. I plan to analyze laminar flow and I need to have zero stress tensor in momentum conservation equation. I guess it can be realized be using udf, but it is not so clear for me how. Note that I can not just use zero viscosity and of course Euler equations are not appropriate for me. On another hand I know that there is C_STRAIN_RATE_MAG(c,t) macro. Will be enough just reset it? I mean set this macro equal zero. If not, do you have any another idea? Could you please help me whit this issue. Thank you in advance.
