Hello I am writing an explicit RKDG code using libmesh. Having read some examples, I am thinking of using a TransientExplicitSystem. Is this the correct approach ?
Since it is explicit, I only need to assemble mass matrix once. In the time stepping only the right hand side needs to be assembled. Being DG, the mass matrix is block diagonal and can be solved per element. Its not clear how to do this. Can you point to some existing examples ? Also I want to use a multi-stage RK like the 3-stage SSP RK scheme of Shu-Osher.
