Interleaved if you want to use Eigen types in the same memory, or if
your code (like most applications) benefits more from memory l
Thanks, so you would suggest a flat vector storing u, v, w (or indeed x, y,
z) or interleaved and then construct eigen types on the fly? Can I ask, is
that because Vec cannot store user defined types (as in it's not
templatetable?)
Thanks,

My suggestion is to use PETSc like usual and inside your
residual/Jacobian evaluation, for each cell or batch of cells, create
Eigen objects. For size 2d or 3d, it won't matter much whether you make
them share memory with the PETSc Vec -- the Eigen types should mostly
exist in registers.
