Multi-component solve using Hypre

[ankithadas]

Dear AMReX team,

Is it possible to set up a multi-component matrix using the HypreSolver? If yes, I am a little bit confused about the stencil size (MSS) in that case ? For example, what would the max stencil size be for Navier Stokes Tensor Solve ?

Kind regards,
Ankith

It's supposed to work with multiple variables. Suppose there are three variables and 100 points for each variable. The matrix and vectors will have 100*3 rows. MSS is the maximum stencil size (i.e., maximum number of non-zeros in a row of the matrix).

Note that HyperSolve has not been used that much. If you notice any issues, please let us know.
