[petsc-users] TS for explicit equations

2017-07-06 Thread Alejandro D Otero

Hello, I'trying to solve an ODE system using PETSc TS through its wrapper petsc4py, and I'm having problems with the setting. The problem is of the kind: u_t = G(t, u) with u being a vector with DoF from a FEM problem and G is computed by a series of matrix operations and manipulations, which are
