GPEC v0.3.3

This release features a critical bug fix for control surface netcdf output and pmodb/xbnormal outputs

• All area normalized or energy normalized quantities were incorrectly converted to the users specified jac_out coordinates. All quantities are now in the DCON jac_type coordinate system unless specifically noted otherwise.
• The jacobian and surface area have been added to the control netcdf as global attributes
• The filtering of singular coupling modes is now done entirely within the DCON coordinate system, for which a new singular coupling matrix is formed and SVD'd.
• Bugs in the use of bcoordsout for pmodb and xbnormal profile quantities that wrote the first variable to multiple variables (i.e. eulb to lagb) were fixed.
• A Bug in the weighting of the bwp profile was fixed

GPEC v0.3.2

• This release features a critical bug fix for control surface ascii output Phi^x.
  • If the jac_out was not the working jac_type Phi^x outputs in the jac_out table were mistakenly in the jac_in coordinate system.
• The external and total flux have been added to the control netcdf alongside their previously stored energy normalized values.

GPEC v0.3.1

Bugfixes

• IPEC fixed mistaken use of Hermitian lapack subroutines for permeability matrix
• PYPEC synthetics properly closes synthetic surfaces that cover the full poloidal angle (vessel wall, etc.)
• PYPEC coil plotting bug fixes for axes and color key words
• PYPEC updated to reflect move from xray to xarray

Features

• IPEC netcdf additions, including control surface matrices, profile quantities, shot/time/machine, and more
• IPEC netcdf names conform to netcdf conventions
• IPEC all netcdf outputs converted to jac_out
• IPEC filter decomposition modes are now all in ascending order (SVD convention)
• IPEC added amplification to filter modes
• COIL added MAST coils
• PENTRC added new grid options, which now include equil_grid or input_grid (i.e. the DCON grid)
• PYPEC improved ascii/netcdf interface using data.open_dataset
• PYPEC synthetics now includes magnetic sensors
• PYPEC add_control_geometry function expands control surface geometry for 2D and 3D plots
• PYPEC improved colormaps and automatic colormap choices
• PYPEC now uses seaborn for context/palettes, has custom set_context function
• PYPEC custom subplots automatically re-size figure to keep axes size
• PYPEC now has png_to_gif function for making movies

Performance

• Improved speed of ipeq_bcoordsout/ipeq_fcoordsout by checking for unnecessary calls to ipeq_fcoords/ipeq_bcoords

GPEC v0.3.0

Bugfixes

• DCON qhigh is enforced independent of sas_flag
• IPEC longstanding bug that caused crashes when brzphi was requested without eqbrzphi is fixed
• IPEC mthsurf bug fixed
  • Benchmarks show perfect recovery of excessively high DCON mthsurf results using mthsurf=1

Features

• COIL now includes 4x48 RFX-mod coils
• IPEC netCDF output is now available for major output flags (more will be transitioned soon)
  • Currently netCDF files include: filter_flag, x/brzphi_flag, xbnormal_flag, pmodb_flag, and control surface fun_flag outputs
• IPEC output subroutines can now be individually timed using the timeit flag
• IPEC mode filtering has a new filter_type, filter_modes interface in IPEC_INPUT
• IPEC reduced terminal printing - no longer is every eigenmode printed to the terminal

Performance

• IPEC speed was increased by saving coordinate transformation information on a surface when performing multiple transformations on one surface
• IPEC brzphi speed was increase by 1-2 orders of magnitude by calculating (r,z,phi) quantities on the requested grid points instead of across surfaces
• IPEC speed can now be confidently increased by a large factor using the mthsurf flag (see bug fix)
• IPEC compiler optimizability increased with the switch from pointers to allocatable arrays

GPEC v0.2.0

Bugfixes

• PYPEC data interpolation changed to use LinearNDinterpolator, handling irregular multidimensional grids.
• Consistent versioning across all programs.

Features

• IPEC reluctance eigenvectors calculated in energy normalized sudo-flux space.
• IPEC mode filters available for energy, reluctance and permeability eigenmodes as well as singular coupling SVD modes.
• PENTRC now explicitly outputs the nonambipolar particle flux and diffusivity.
• PENTRC now capable of calculating neoclassical heat flux and diffusivity.
