Grid Parameters
The &grid
namelist group defines the parameters used to set up
the spatial grid, as follows:
scaffold_src
(default'MODEL'
)Source for scaffold grid; one of:
'MODEL'
: Obtained from the stellar model'FILE'
: Read from a file (see thefile
andfile_format
parameters)
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
(default0
)Oscillatory weighting parameter \(w_{\rm osc}\)
w_exp
(default0
)Exponential weighting parameter \(w_{\rm exp}\)
w_ctr
(default0
)Center weighting parameter \(w_{\rm ctr}\)
w_thm
(default0
)Thermal weighting parameter \(w_{\rm thm}\)
w_str
(default0
)Structural weighting parameter \(w_{\rm str}\)
dx_min
(defaultSQRT(EPSILON(1._WP))
)Minimum spacing of grid points
dx_max
(defaultHUGE(0._WP)
)Maximum spacing of grid points
n_iter_max
(default32
)Maximum number of refinement iterations
resolve_ctr
(default.TRUE.
)Flag to resolve central evanescent region
file
(default''
)Name of file containing scaffold grid data (when
scaffold_src
='FILE'
)file_format
(default''
)Format of file containing scaffold grid data (when
scaffold_src
='FILE'
); one of:'TEXT'
: text file with one abscissa value per line'DETAIL'
: detail file with abscissa values provided inx
dataset
tag_list
(default''
, which matches all)Comma-separated list of
&mode
tags to match
See the Spatial Grids section for further details, in
particular a discussion of how the weighting (w_*
) parameters
work.
