Hello, once more again > > 71874 dofs for Cahn-Hilliard part of system, cca 2000-3000 dofs per computer > core
I have solved the Navier-Stokes-Cahn-Hilliard system on 32 cores as decoupled. Algorithm: 1)assemble, solver Cahn-Hilliard ->71874 dofs 2)assemble,solve Navier-Stokes -> 2773956 dofs Therefore ad1) is split into small subsystems (approximately 2000 unknowns for each core) and therefore the Amesos_Superludis should have worked nicely? Hasn't it? I admit that concerning the ad)2 is your remark sound.
