.. _Chap:InputsHypre:
Hypre Inputs
=============
The following inputs control the hypre settings and are read directly
by AMReX when we use hypre as the bottom solver.
NOTE: Default uses the same hypre namespace "hypre" for all solvers. However,
the hypre namespace can be set at the solver level and the hypre settings
can be configured for each MLMG solver.
These settings must be preceded by the hypre_namespace setting corresponding to the solver (see :ref:`Chap:InputsMultigrid`)
