[petsc-users] PCMG behaviour on various levels

Hi, Quick PCMG question. Default behaviour of PCMG (I'm using 3D DMDAs) is to use all processes for every level and redundantly solve the coarse level locally (to my knowledge). However, if I want to keep the level numbers to be log_c N for (c=2^d, d=dimension, N = dof of finest mesh) so that

[petsc-users] When is the TSMonitor called?

Hi all I want to save a certain quantity at the very beginning of each time step, before any TSFunction of any kind is called. Can I do this within the TSMonitor? It would also be ok to save that quantity at the very end of the time step. Thanks Miguel -- *Miguel Angel Salazar de Troya*

[petsc-users] 3D multi-dof DMDA and Poisson equation

Hi, I am making a new, simple incompressible CFD code. I have created a grid as a 3D DMDA, with ndof=4, one dof for each velocity component (u,v,w) and one for the pressure (p). Currently I am creating a forward Euler step, where the velocities are updated based on the velocities and
