Greetings, I am a master’s student in TU Delft, The Netherlands, and I am carrying out my thesis using the adaptive mesh refinement solver provided in ./ts/tutorials/ex11.c.
In the process of my work, I have added a HLL Riemann Solver for the shallow water equation. I had already tested and validated the Riemann Solver using several cases (I am happy to provide a copy of my thesis report). It would indeed be nice to see my work reflected in the current version of ex11.c as an addition to its capability. Furthermore, I had also added a Riemann Solver that contains topography terms and is well-balanced*. The caveat is that I see that there some variations in the well-balancedness when choosing between p4est and Plex DM’s. Perhaps, this could be looked at and fixed in the future. The purpose of this email is to propose the addition of the HLL Riemann Solver for the shallow water equations to ex11.c and perhaps later explore the possibility of adding the Riemann Solver with the bathymetry terms. I have already gone through the CI process instituted by PETSc (previously integrated ./ts/tutorials/ex54.c into the repository with the valuable assistance of Mr. Satish Balay). Hence, I would be more or less familiar with the process. I kindly ask you provide any feedback on this proposition. Regards, Mukkund Sunjii
