Dear Foamers,
I still try to implement a special update scheme in the interFoam solver (https://doi.org/10.1016/j.jcp.2019.109067). The scheme requires to sequentially solve the equations inside the domain. From what I understand right now (I just started to work with OpenFOAM a few weeks ago), an equation is set-up according to: A*u=b where A is the matrix containing the coefficients from the implicit parts, u containing the values after the update in the step .solve() and b containing source terms and explicit parts, right? What I would like to do know is to extract a number of rows from A, u and b and solve this subsystem. Is there an straight forward way in OpenFoam to handle this kind of operation? I hope my question got clear, otherwise don't hesitate to ask. I really appreciate any kind of help. Thanks a lot, Axel |
