3153 var missing in plot proc.py

[chris-ashe]

Description

There has been several problems in plot_proc.py that prevent it from showing all of the variables correctly and formatted neatly

Changes include:

• The dark blue WP is now no longer plotted in the toroidal cross-section plot as this would normally overlap with the TF coil case lines. The TF plotter on page 3 now does this better.
  

• The "plasma" and "cryostat" labels have been removed from the toroidal cross-section plot to prevent cluttering.

• The vertical thermal shield (thsield_vb) was not importable as it was not outputted to the MFILE, this is now resolved.

• The width of the neutral beam duct (beamwd) was being outputted to the MFILE with its default value when a design did not use NBI, this has now been removed from the output.

• The spacing between the label names and colours for the cross section plots have been spaced out to prevent overlap of text.

• Variable descriptions all now have correct capitalisation.

• Change of list indexing now sees plot_proc.py know the correct number of PF coils. Preventing rpf[n] not found errors.

• The colour legend is now moved to the top right of the first page to prevent clashing with the plasma composition output
  

• The inclusion of fixed secondary heating and current drive is now properly implemented preventing NaN errors and saying there is secondary heating when it is not present.

• wwp2 is now only imported when the WP design that uses it (i_tf_wp_geom == 1) is used. It was previously wrongly imported when i_tf_turns_integer == 0.

• nbshield, rtanbeam, rtanmax and beamwd are now only imported when NBI is used, as they are not in the MFILE otherwise.

• Scaling law name output is now back thanks to Add tauelaw back to mfile #3156

• i_tf_wp_geom and i_tf_case_geom output has now been fixed to show integers as they are switch variables.

• kallenbach_switch has been removed as the Kallenbach models are no longer used.

• Outputs using alstrtf have been removed as the variable is obsolete.

• Spacing between all output labels and values has been increased to prevent overlap.

• The numbering of the PF coils has been better adjusted to fit properly within the boxes without colliding with the box edges

• "Th shield" is now "Thermal shield" in the plotting key.

• NB duct is now only shown in the colour key when NBI is present

• A new colour scheme has been added for the cross sections to match that used in BLUEMIRA, it can be set in the CLI with --colour
  

• The plasma colour fill now completely fills the plasma boundary with no over spill

Checklist

I confirm that I have completed the following checks:

• I have justified any large differences in the regression tests caused by this pull request in the comments.
• I have added new tests where appropriate for the changes I have made.
• If I have had to change any existing unit or integration tests, I have justified this change in the pull request comments.
