This change replaces the `coreprofiles` module with a new `gray_plasma`
module providing the same functionality without using global variables.
- `read_profiles`, `read_profiles_an` are replaced by a single `load_plasma`
routines that handles both profiles kind (numerical, analytical).
- `scale_profiles` is merged into `load_plasma`, which besides reading
the profiles from file peforms the rescaling and interpolation based
on the `gray_parameters` settings.
- `set_profiles_spline`, `set_profiles_an`, `unset_profiles_spline`
are completely removed as the module no longer has any internal state.
- `density`, `ftemp`, `fzeff` are replaced by the `abstract_plasma`
type which provides the `dens`, `temp` and `zeff` methods for
either `numeric_plasma` or `analytic_plasma` subtypes.
1. Use the `contour` type for limiter and plasma boundary
(rlim, zlim, rbnd, zbnd)
2. Replace `inside` with `contour%contains`
3. Replace `range2rect` with a `contour` interface
4. Remove the limiter module which just re-exports the limiter
as a global; instead just pass the contour object around
This change replaces the output files (Fortran units) with a derived
type called table, that hold the data in memory until further
processing. The data stored in a table can be dumped to a file, as
before, or processed in other ways, for example converted to other
derived type.
In the case of analytic equilibrium without a limiter contour, the
simple limiter was built incorrectly due to an unnecessary conversion
from cm (the equilibrium data are already in metre).
This adds a new `splines` module which implements a high-level interface
for creating and evaluating splines and rewrite almost all modules to
use it. Also, notably:
1. both `simplespline` and DIERCKX splines can now used with a uniform
interface
2. most complexity due to handling working space arrays is gone
3. memory management has been significantly simplified too
This adds a new configuration file based on the INI format.
The new format will allow adding GRAY parameters without breaking
compatibility with existing configurations, unlike as of the old
gray_params.data.
This change structures the arguments of most functions, in particular
gray_main, into well-defined categories using derived types.
All types are defined in the gray_params.f90 (location subject to
change) and are organised as follows:
gray_parameters (statically allocated data)
├── antenna_parameters
├── ecrh_cd_parameters
├── equilibrium_parameters
├── misc_parameters
├── output_parameters
├── profiles_parameters
└── raytracing_parameters
gray_data - inputs of gray_main (dynamically-allocated arrays)
├── equilibrium_data
└── profiles_data
gray_results - outputs of gray_main (dynamically-allocated arrays)
