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
w_osc (default 0)
Oscillatory weighting parameter \(w_{\rm osc}\)
w_exp (default 0)
Exponential weighting parameter \(w_{\rm exp}\)
w_ctr (default 0)
Center weighting parameter \(w_{\rm ctr}\)
w_thm (default 0)
Thermal weighting parameter \(w_{\rm thm}\)
w_str (default 0)
Structural weighting parameter \(w_{\rm str}\)
dx_min (default SQRT(EPSILON(1._WP)))
Minimum spacing of grid points
dx_max (default HUGE(0._WP))
Maximum spacing of grid points
n_iter_max (default 32)
Maximum number of refinement iterations
resolve_ctr (default .TRUE.)
Flag to resolve central evanescent region
tag_list (default '', which matches all)
Comma-separated list of &mode tags to match

See Spatial Grids for further details, in particular a discussion of how the weighting (w) parameters work.
