Hello, In FiPy code, how do I solve for the phase field interface velocity using the advection equation? I found the following post, but I am in need of some more detailed instruction:
http://www.mail-archive.com/[email protected]/msg00115.html After looking through the level set examples, I think I can set up the advection equation, but I am not sure how to solve for the velocity only in the interface region (where the derivative of the phase field variable is not zero). Before I try and solve my own problem, I would like to compare the velocity as calculated using the advection equation to the velocities already found in examples/phase/simple, so that I know I am correctly solving for it. Thanks, Ryan
