Grid ParametersΒΆ

The &grid namelist group defines the parameters used to set up the calculation grid; the input file can contain one or more, but only the last (matching) one is used. Allowable parameters are:

x_i (default based on model grid)
Inner boundary coordinate of calculation grid
x_o (default based on model grid)
Outer boundary coordinate of calculation grid
alpha_osc (default 0)
Oscillatory resampling parameter \(\alpha_{\rm osc}\)
alpha_exp (default 0)
Exponential resampling parameter \(\alpha_{\rm exp}\)
alpha_thm (default 0)
Thermal resampling parameter \(\alpha_{\rm thm}\)
alpha_str (default 0)
Structural resampling parameter \(\alpha_{\rm str}\)
dx_min (default SQRT(EPSILON(1._WP)))
Minimum spacing of grid points
n_inner (default 0)
Number of extra point to insert at center
n_floor (default 0)
Minimum total number of grid points
n_iter_max (default 8)
Maximum number of refinement iterations
tag_list (default '', which matches all)
Comma-separated list of &mode tags to match

See Understanding Grids for further details, in particular a discussion of how the alpha_* resampling parameters work.
