The current version of SPENVIS is 4.6.3.  Because of the complexity of some models and simulations, the access to the models is provided in two flavours: as normal or advanced user.

New models since 4.6.3 are
  • Mars Energetic Radiation Environment Models (MEREM);
  • Relative Damage Coefficient converter;
  • Magnetocosmics and Planetocosmics Geant4 tools;
  • NeQuick model (see Ionosphere constituent fluences);
  • PSYCHIC model (see Solar proton fluences);
  • MC-SCREAM model for solar cell degradation.
Other upgrades in 4.6.3 are
  • Single Event upset rates (19 predefined devices, user-defined path length distribution, non-constant LET across the sensitive volume);
  • IGE-2006 wizard;
  • Geant4 tools (user interface);
  • index page (help).
  • Result export facility (here)

New feature in 4.6.2 is
  • Pre-release of a java-based geometry definition tool (here).
Upgrades made in 4.6.2 are
  • Help pages (correction of broken links);
  • ECSS space environment standard;
  • SPENVIS kernel.

Features for advanced users include
  • switching to another planet and accessing Martian or Jovian models;
  • execution of Combined Run;
  • additional options in some models (e.g. orbit generator, NIEL, SEU rates);
  • upload of data files (e.g. trajectory, Geant4 geometry, RDC).

Announcement
Currently the use of SPENVIS is free of charge.  In a near future, a subscription-based service offering various options will be implemented.  However an access free of charge will still be offered.  This access will be fully functionnal but with reduced quota and result persistence.
