SPIS

Spacecraft Plasma Interactions System Documentation

The Spacecraft Plasma Interaction System, SPIS, is a simulation software based on an electrostatic 3D unstructured Particle-In-Cell plasma model and consisting of a JAVA based highly modular Object Oriented library, called SPIS/NUM. More accurate, adaptable and extensible than the existing simulation codes, SPIS is designed to be used for a broad range of industrial and scientific applications. The simulation kernel is integrated into a complete modular pre-processing/computation/postprocessing framework, called SPIS/UI, allowing a high degree of integration of external tools, such as CAD, meshers and visualization libraries (VTK), and a very easy and flexible access to each level of the numerical modules via the Jython script language. Developed in an Open Source approach and oriented toward a future community based development, SPIS is already partially available for the whole community and is used by members of the European SPINE network. SPIS should address a large majority of the new challenges in spacecraft plasma interactions, including the environment of electric thruster systems, solar arrays plasma interactions, and accurate calibration of scientific plasma instruments.

SPIS has been initially developped by ONERA, the Artenum Company and the Paris 7-Denis Diderot University, with the support of the European Space Agency (ESA/ESTEC Contract Nb 16806/02/NL/JA).

SPIS-NUM Documentation

• SPIS-NUM User pages
• Num tips: a list of brief HowTo questions, a kind of "Frequently Asked Questions" of Num.
• SPIS/NUM Controlling NUM from UI: Explains how to set all control parameters in User Interface to define Numerical simulations, the user reference documentation.
• Spacecraft circuit: how the spacecraft equivalent circuit is defined in SPIS from user parameters.
• ESD models documentationDevelopment of a predictive discharge numerical model on solar panels - Final Report.
• SPIS-NUM Developer pages
• Java for NUM: basic information on Java language and conventions useful for SPIS/NUM (+ edition and debugging)
• NUM architecture: description of object architecture of SPIS/NUM, for an overall understanding of how it works.
• NUM integration in framework: how to integrate SPIS/NUM modified code in the framework.
• Writing UI-supported classes: how to develop classes which the UI can order NUM to switch to.
• SPIS-NUM Technical Notes
The detailed documentation of each solver as part of the API documentation. However some solvers deserved more thorough explanations and specific pages were written for that:
• Circuit solver
• Particle-In-Cell model
• Charge exchange model
• Finite element model for the electric field
• Multi-physics and mutli-domains solvers: Algorithms and technical description.
• SPIS-NUM API documentation (Application Program Interface)
Following Java documentation logics, all source code have been documented in details in Javadoc format, and resulted in a very rich API documentation, also containing information on solver models:
SPIS_NUM public members
• SPIS_NUM private members
• SPIS-NUM Tutorials, Courses and HowTo
• A database of courses and talks given at SPINE Workshops 5 to 10, mostly dedicated to SPIS (+ papers at SCTC conferences).
• SPIS-NUM Java Programming, rules and methods
• SPIS/NUM How to integrate the numerical core
• SPIS/NUM Presentation of SPIS-NUM
