Hi all, After an evaluation of the demonstration version (downloaded from pdesolutions web site), I come up to conclude that flexPde is a good piece of software for FE analysis in different field of physics. However, since I couldn't experiment it with my own problem, I would like to know a couple of things about its capability to solve some specialty problems related to fluid flow. Among those, a common problem is that of immiscible (incompressible or weakly compressible) two-phase flow where an injection fluid displaces the other, along a sharp interface moving with time. The position of this interface is a part of the solution problem, which is described by two pde's for each fluid, and other equations expressing the continuity of pressure and fluids velocity along this interface. Does anyone solves a similar problem with flepde? Thank you if you could answer or suggest some solutions, to help me in my decision if the software is suitable for my research work. | ||

You can get a free 30-day trial license to FlexPDE by sending us the Computer ID reported on the Register dialog, along with some information about yourself (name, address and company or institution) to sales@pdesolutions.com The problem "Samples | Time_Dependent | Chemistry | Melting.pde" solves a similar problem to the one you describe, at least insofar as the phase-change boundary is concerned. "Samples | Time_Dependent | Fluids | Black_Oil.pde" solves the same problem as the one you describe. It is the expulsion of oil from a reservoir by injection of water. The interface is not sharp in this problem, however. | ||

Hi, Yes I have done this with Flex for saltwater intrusion simulations. Contact me at vbense@indiana.edu for info, Victor |
