[petsc-users] TS and snes_grid_sequence

[Francesco Magaletti]

Dear Jed and Emil, 
your suggestion to use L-stable time integrators gave great results, since the SNES now converges with higher timestep values. 
The arkimex 2e performs very well, in particular with the extrapolation of the initial guess. 

Thank you for your time

Francesco
