Hi all, So apparently I was somehow lucky when the below worked. If I use a different mesh, for example as in ex6 under systems_of_equations, the options below do not work. I get the error: [0]PETSC ERROR: Nonconforming object sizes! [0]PETSC ERROR: Index set does not match blocks! I've tried

Hi all, I'm solving a large 3D linear elasticity (steady) problem. My mesh has 8.8million nodes, so since this is a vector-valued problem there's around 26 million unknowns. The code is basically systems_of_equations_ex6 (except for the mesh generation part, and I also do not compute stresses
