Hey Everyone,

So I am utilizing SolidWorks Flow simulator package and I am trying to investigate how well methane and air mix on a certain surface of my model. The model is set up to converge with surface goals, the goals that are set up are the volume fraction of air and methane. The problem I run into is that when I set my pressure outlet boundary condition I have to set a substance concentration at the outlet, and I feel that this boundary condition effects my results from my model. Is there anyway to set up a outlet condition without having to specify the substance concentrations?

The model is too big to post on this thread but I can e-mail if requested.
