Sara28 New Member Join Date: May 2015 Location: Germany Posts: 15 Rep Power: 11	Hey everybody, i want to know how fast different gases diffuse. For this i wanted to give Fluent different concentrations between inlet and outlet and calculate the diffusion. How can i insert such an concentration gradient? Is there something else i have to consider when simulating diffusion? Please reply! Thanks!
