Dear all, Yesterday I sent this email, because of the attachment, email is too big, so I send it again.:) I work on fully implicit polymer solvers for a long time, I think it’s time to discuss with you about them. Last year, I visited SINTEF, meet with Atgeirr , Bård , Xavier and other nice developers, with their help, the fully implicit polymer solver make great progress.
Currently, Fully implicit polymer solvers just are two-phase which based on opm-autodiff and opm-polymer. Because we want to start with incompressible flow, so first at all, I create an fully incompressible two-phase simulator, for this simulator, I neglect all of the compressibility, but capillary and gravity are included. The main structure of the solver is similar with opm-autodiff/FullyImplicitBlackoil.cpp, just copy and modify that file to create the new solver. I notice that there are many new features coming into both opm-core and opm-autodiff, I hope I can follow them, but it needs time, for the current incompressible simulator, I just apply the new well controls. I did a simple test, the result is almost the same with Atgeirr’s. Later, I will make a pull request to open it, any comments are appreciated. For the fully implicit polymer simulator which include both incompressible and compressible flow, has the following features: 1. Adsorption 2. Permeability reduction 3. IPV 4. Todd-Longstaff mixing 5. Keyword “WPOLYMER” The equations which we use are the same with ECLIPSE, and also the parameters. We did several tests, including 2D and 3D,more realistic test cases are going on. We found that our result has a perfectly match with ECLIPSE. Beside the current features, we are going to implement shear model, this needs some time. If it is possible, I would like the fully implicit polymer simulator be part of the OPM next release, but there are some issue need to be discussed: 1. Currently , all of our codes are put in opm-polymer, so this means opm-polymer require opm-autodiff, this could be a question, because I don’t know If this change can bring somethings bad to OPM. 2. I know that new parser is coming, I need to catch up with them, but I have not apply the new features to the polymer simulators, if the polymer solver want to attend the next OPM release, a lot of work need to be done, I hope someone else who familiar with that can help me, I will appreciated. I am a new developer , there must be a lot of shortcomings, I am looking forward to your comments. Have a nice day!
