Hello everyone,
I am using OpenFOAM v6 to do some 3D combustion simulation which also produces shocks. My cases are running but the resolution is so poor. I am currently utilizing a structured mesh of 10 Million cells. My current fvschemes file is given below.

So, my goal is to increase the resolution. How can I achieve that?

Do I adjust the schemes or the mesh?

In terms of schemes, which schemes can I use to get a good resolution?

In terms of mesh size, if I change to unstructured mesh with 25 - 30 million cells will increase my resolution considerably.

Thanks for the answer.
