Dear Developers,<br><br>can you please suggest me a valid alternative to using KSPGMRES in combination with PCASM for parallel runs on unstructured meshes in cases involving compressible flows (so, convection dominated problems, including high-speed, shocks and so on)? I would like to explore some of the latest features such as variants of MG / AMG, but would you expect them to work in such applications? what are the most conservative settings I could use to start with?<br>
