Description: The whole package of OMERE 5.3

Last releases

Novelties:

• OMERE v5.3 is available in version 64-bits.
• Integration of the average SAPPHIRE models for heavy ions.
• Integration of the solar flares SAPPHIRE models for protons and heavy ions.
• Integration of the GREEN-electrons and GREEN-protons models (trapped particles). Note that these models provide only integrated fluxes.

Improvements:

• The advanced manual has been merged with the regular user manual. It can now be accessed directly via the “advanced section” of the help menu.
• Management of versions has been improved where users installed several versions of OMERE on their computer.

Corrections:

• Solar particles: integration constant was missing after the application of the magnetospheric shielding.
• Fix of several minor issues.

Corrections

  • Solar cells: isotropy of spectrum was not correctly considered
  • SEE module: restoration of the Bendel fit.
  • Default Path files were not set correctly
  • Dose curve calculation: when changing the target material several times, the calculation did not take the new material into account.

Improvements

  • The METIS model is now available when HI cross-sections data are in cm²/device.
  • The SEE section in the help menu has been updated.
  • In the “Equivalent LET” module: several plots can be overlaid.

Corrections

  • Minor bugs have been fixed in the SEE module.
  • Module Atomic Displacement: the calculation “along the orbit” is now available when “displacement dose file” is selected.

Improvements

  • The version of AE9/AP9 has been updated to v1.50
  • The datac folder is now installed in another folder. This fixes a crash for computers on WINDOWS10.

Corrections

  • Solar particles: software crashed when plotting solar ions
  • Solar particles: the shielding was not taken into account for ions models.
  • GCR: correction of the spectrum calculation with the “mission” option for GCR ISO 15390 model.

  • AE9/AP9 v1.30 models (trapped particles)
  • SAPPHIRE model for protons and Helium (solar particles)
  • METIS model for proton cross sections calculation.

Major improvements

  • Redesign of the Orbit dialog. For orbit files, possibility to change the order of the columns.

  • Redesign and optimization of the dose module.
  • Improvement of the calculation time with SLOT and OZONE module.
  • Shieldose: code optimisation & multi-threading.

Others

Update of IGRF magnetic field at IGRF-12 version

Corrections:

  • Transport: transport of multiple proton files did not take into account the first incident flux file.
  • LET spectrum: the calculation with the shielding geometry from a sector file was not possible.

Corrections:

  • Windows 10: The trapped particle dialog was causing a crash.
  • Transport: Shielding thickness <01 g.cm-1 led to unchanged integral flux values.

Corrections:

  • Trapped particle module: Magnetic field models given in result files could be different from the selected models on the GUI. However the computations used the models selected by the user.
  • SEE rate calculation module: correction of the X axis unit of the Weibull curve display for heavy ions from energy to LET.
  • GCR flux calculation module: The elements of the periodic table are now always updated automatically when switching from one element to another having a lower Z. This fix prevents a crash during the computations.
  • SEE rate calculation module: correction of the SEE rate computations based on an integral LET file.
  • Dose calculation module: dose depth curve graphs can now be overlaid only if their unit is the same.
  • The date format in the output file of the instantaneous flux has been changed to increase their precision.
  • Cosmic Rays module: correction on the calculation of the flux for the GCR ISO 15390 model with the Mission

Improvements

    • Transport module: the results of the electron flux transport have now a fixed sampling (10 samples per decade) that is extended down to 1 keV.
    • Graph plotting: plotting a graph from a file allows again overlaying graphs. Information about axis and units are also retrieved from the file if they exist and are correctly formatted.

Modifications

  • Modification of the default name for the output file of the thickness table in dose calculation parameters.
  • Modification of the output file name when post-processing SEE using multi-mission tool.
  • Temporary removal of ‘O-Scream’ in the ‘Solar Cells’ menu.
  • Modification of the help of ‘Optimization and uncertainty estimation’ in SEE menu and addition of a pop-up message.

Corrections

  • Correction of a bug in the consideration of flux units for SEE rate calculation with a proton integral flux file.
  • Correction of a bug in the display of integral fluxes of solar flare particles previously plotting differential fluxes.
  • Correction of the displayed unit for the dose depth curve depending on the chosen one in ‘SPECIALS’ parameters.

  • Trapped particles module: temporary removal of the COMBI model for electrons, a problem with the flux calculation needs to be corrected
  • SEE: correction of periodic flux file reading when file contains calculation steps with no fluxes
