Section: amr

This section contains input parameters used by the core AMReX mesh data structure AmrCore to determine the base mesh and adaptive mesh refinement strategies. The refinement criteria is specified through Section: AMR Tagging

amr.n_cell

type: List of 3 integers, mandatory

The number of cells in the coarset level of AMR hierarchy

amr.max_level

type: Integer, optional, default: 0

The maximum AMR level in the refinement hierarchy. Default value is 0 indicating a single mesh level with uniform resolution in the three directions.

amr.max_grid_size

type: Integer, optional, default: 32

Maximum number of cells at level 0 in each grid. There are also options to specify this value in each direction, please refer to AMReX documentation.

amr.blocking_factor

type: Integer, optional, default: 8

Each grid must be divisible by amr.blocking_factor. There are also options to specify this value in each direction, please refer to AMReX documentation.
