This is the core distribution of ArtiSynth, a 3D mechanical modeling system that supports the combined simulation of multibody and finite element models, together with contact and constraints. While targeted at biomechanical and biomedical applications, it can also be used for general purpose mechanical simulation. It is freely available under a two-clause BSD-style open source license. The system is implemented in Java, and provides a rich set of modeling components, including particles, rigid bodies, finite elements with both linear and nonlinear materials, point-to-point muscles, and various bilateral and unilateral constraints including contact. A graphical interface allows interactive component navigation, model editing, and simulation control. Full details, videos and documentation are provided on the ArtiSynth website at https://www.artisynth.org. For details on how to install artisynth_core from Github, see the section "Cloning from Github" in the installation guide appropriate to your system at https://www.artisynth.org/doc/info/installation. ======================================================================= Files in this directory: .artisynthInit Default ArtiSynth initialization file .classpath Classpath information used by the Eclipse IDE .demoModels List of "banner" demo models available when ArtiSynth starts up .git* If present, contain repository and configuration information used by the Git SCM. .mainModels List of "banner" anatomical models in the ArtiSynth Models package (which must be installed). .project Project information used by the Eclipse IDE ArtiSynth.launch Default "launch" configuration for used by the Eclipse IDE ArtiSynth_launch Backup copy of the default version of ArtiSynth.launch .settings/ Settings information used by the Eclipse IDE DISTRO_EXCLUDE Describes any files that should be excluded from the current precompiled distribution.
