Hi, Specifying a Neumann flux BC seems to have fixed the issue (while the previous flow were driven only by the saturation Dirichlet).

Thanks Christoph. _____________________________________________ From: Shawn Zhang [mailto:[email protected]] Sent: Thursday, September 25, 2014 09:55 To: [email protected] Subject: Large nonphysical non-wetting fluid satuation near outlfow boundary Hi Dear Dumux Experts, While running a simple decoupled 2p example, I noticed large saturation numbers near outflow boundary, e.g., 44.5, which are completely unphysical. I attached below a screenshot illustrating this observation. I tested the outlet with both outflow boundary condition and Dirichlet boundary condition, with the same results. If I visualize only the data between 0 and 1, the results appear to be reasonable in the rest of domain. Have you seen this in the past? Can I just remove those boundary cells when I compute additional parameters? Your advice and guidance will be greatly appreciated.
