Does the new version supersede the previous version?: Yes

Nature of problem:
High precision simulation of relativistic many-body systems.

Solution method:
High precision calculations based on BigInteger .Net Framework 4.0 new feature.

Development of a high precision framework

Summary of revisions:
  • Development of a new high precision module
    • Undefined precision framework based on the new BigInteger .Net Framework 4.0 structure
    • High precision relativistic many-body engine
  • Chaos Analysis Tools
    • Implementation of Phase Space distance between two N-Body systems, as a function of time
    • Implementation of a decimal (base 10 number representation) version of the Chaos Analysis Tools
    • Implementation of a probability distribution tool (Analysis\Chaos Analysis\Other Tab)
    • Implementation of usual relativistic formulas for facilitating processing of Monte Carlo log files (Analysis\Relativistic Formulas XLS). Microsoft Excel is a requirement for this functionality.
  • Bug Fixes
    • In the particular case of two identical particles head-on collisions, reactions were not treated in earlier versions of CMBE.
  • Examples of use
    • Using 46 digit precision for analyzing the Gravitational Butterfly Effect in a specific relativistic nuclear collision toy-model
    • Simplified nuclear relativistic collisions toy model for analyzing the Gravitational Butterfly Effect (High Precision\Gravity)
    • Simplified model for analyzing the Cumulative Effect (relativistic nuclear collisions for target nuclei containing one or more alpha particle(s))

Additional comments:
XCopy deployment strategy.

Running time:
Quadratic complexity, around 2 hours for one C+C event, 50 Fm/c, on a dual core @ 2.0
