It allows you to explore the\nphysical world through simulations.\n\nFeatures\n\n - Classical mechanical simulation in two dimensions\n - Particles, springs with damping, gravitational and coulomb forces\n - Rigid bodies\n - Collision detection (currently only discrete) and handling\n - Soft (deformable) bodies simulated as user-editable particles-springs\n   systems, sound waves\n - Molecular dynamics (currently using Lennard-Jones potential): gas and\n   liquid, condensation and evaporation, calculation of macroscopic quantities\n   and their variances\n - Unit conversion and expression calculation: you can enter something like\n   (2 days + 3 hours) * 80 km/h and it will be accepted as distance value\n - Error calculation and propagation: you can enter values like 1.3 +/- 0.2\n   for any property and errors for all dependent properties will be calculated\n   using statistical formulas\n - Solver error estimation: errors introduced by the solver are calculated and\n   added to user-entered errors\n - Several different solvers: up to 8th order, explicit and implicit, with or\n   without adaptive timestep\n - Controller tool to easily change properties during the simulation, including\n   customizable keyboard shortcuts\n - Tools to visualize results: graph, meter, tracer\n - Context information for all objects, integrated wikipedia browser\n - Collection of example experiments and integrated tutorials\n","package_architecture":"amd64","stem":"step","readme":null,"dependencies":[{"path":"devel/gsl","type":"library","package_spec":"","url":"/packages/release/devel/gsl/"},{"path":"devel/kf6/attica","type":"library","package_spec":"","url":"/packages/release/devel/kf6/attica/"},{"path":"devel/kf6/kcolorscheme","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kcolorscheme/"},{"path":"devel/kf6/kcompletion","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kcompletion/"},{"path":"devel/kf6/kconfig","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kconfig/"},{"path":"devel/kf6/kconfigwidgets","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kconfigwidgets/"},{"path":"devel/kf6/kcoreaddons","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kcoreaddons/"},{"path":"devel/kf6/kcrash","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kcrash/"},{"path":"devel/kf6/ki18n","type":"library","package_spec":"","url":"/packages/release/devel/kf6/ki18n/"},{"path":"devel/kf6/kiconthemes","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kiconthemes/"},{"path":"devel/kf6/kio","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kio/"},{"path":"devel/kf6/kjobwidgets","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kjobwidgets/"},{"path":"devel/kf6/knewstuff","type":"library","package_spec":"","url":"/packages/release/devel/kf6/knewstuff/"},{"path":"devel/kf6/kplotting","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kplotting/"},{"path":"devel/kf6/kservice","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kservice/"},{"path":"devel/kf6/kguiaddons","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kguiaddons/"},{"path":"devel/kf6/ktextwidgets","type":"library","package_spec":"","url":"/packages/release/devel/kf6/ktextwidgets/"},{"path":"devel/kf6/kwidgetsaddons","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kwidgetsaddons/"},{"path":"devel/kf6/kxmlgui","type":"library","package_spec":"","url":"/packages/release/devel/kf6/kxmlgui/"},{"path":"devel/kf6/sonnet","type":"library","package_spec":"","url":"/packages/release/devel/kf6/sonnet/"},{"path":"math/libqalculate","type":"library","package_spec":"","url":"/packages/release/math/libqalculate/"},{"path":"x11/qt6/qtbase","type":"library","package_spec":"","url":"/packages/release/x11/qt6/qtbase/"},{"path":"misc/shared-mime-info","type":"runtime","package_spec":"","url":"/packages/release/misc/shared-mime-info/"},{"path":"devel/desktop-file-utils","type":"runtime","package_spec":"","url":"/packages/release/devel/desktop-file-utils/"},{"path":"x11/gtk+4,-guic","type":"runtime","package_spec":"","url":"/packages/release/x11/gtk%2B4,-guic/"},{"path":"devel/kf6/kdoctools","type":"runtime","package_spec":"","url":"/packages/release/devel/kf6/kdoctools/"},{"path":"math/eigen3","type":"build","package_spec":"","url":"/packages/release/math/eigen3/"},{"path":"devel/gettext,-tools","type":"build","package_spec":"","url":"/packages/release/devel/gettext,-tools/"},{"path":"devel/kf6/kdoctools","type":"build","package_spec":"","url":"/packages/release/devel/kf6/kdoctools/"},{"path":"devel/kf6/extra-cmake-modules","type":"build","package_spec":"STEM->=6.23.0","url":"/packages/release/devel/kf6/extra-cmake-modules/"},{"path":"graphics/vulkan-loader","type":"build","package_spec":"","url":"/packages/release/graphics/vulkan-loader/"},{"path":"x11/qt6/qttools","type":"build","package_spec":"","url":"/packages/release/x11/qt6/qttools/"},{"path":"devel/cmake/core","type":"build","package_spec":"STEM->=4","url":"/packages/release/devel/cmake/core/"},{"path":"devel/ninja","type":"build","package_spec":"","url":"/packages/release/devel/ninja/"},{"path":"archivers/xz","type":"build","package_spec":"STEM->=5.4.0","url":"/packages/release/archivers/xz/"}],"reverse_dependencies":{"count":1,"url":"/packages/data/a2/a288b26bd6766f6d4a0c451e8ab84819bfeae2f1b7a9cca065f5cab1ea44fa37.json"},"categories":["education","math","x11/kde-applications"],"flavors":[],"only_for_architectures":["aarch64","amd64","arm","i386","mips64","mips64el","powerpc","powerpc64","riscv64","alpha","hppa","sparc64"],"not_for_architectures":[]}}
