[petsc-users] Guidelines for solving the euler equations with an implicit matrix free approach

[Kontsantinos Kontzialis]

Dear Petsc team,

  I'm new in Petsc and I'm trying to solve the euler equations of fluid 
dynamics
using an implicit matrix free approach with a spatial discontinues 
galerkin discretization.
I need some directions about how can I solve the following system:

(M/dt+dR/du)*DU=R

where R denotes the residual of the system and dR/du the residual 
jacobian. Please help.
