In the attachment you will find a new tarball which contains a new description with input and tweaks from schwarze@ (Thanks!). Information for inst:step-18.08.2 Comment: KDE interactive physics simulator Description: Step is an interactive physical simulator. It allows you to explore the physical world through simulations. Features - Classical mechanical simulation in two dimensions - Particles, springs with damping, gravitational and coulomb forces - Rigid bodies - Collision detection (currently only discrete) and handling - Soft (deformable) bodies simulated as user-editable particles-springs systems, sound waves - Molecular dynamics (currently using Lennard-Jones potential): gas and liquid, condensation and evaporation, calculation of macroscopic quantities and their variances - Unit conversion and expression calculation: you can enter something like (2 days + 3 hours) * 80 km/h and it will be accepted as distance value - Error calculation and propagation: you can enter values like 1.3 +/- 0.2 for any property and errors for all dependent properties will be calculated using statistical formulas - Solver error estimation: errors introduced by the solver are calculated and added to user-entered errors - Several different solvers: up to 8th order, explicit and implicit, with or without adaptive timestep - Controller tool to easily change properties during the simulation, including customizable keyboard shortcuts - Tools to visualize results: graph, meter, tracer - Context information for all objects, integrated wikipedia browser - Collection of example experiments and integrated tutorials Maintainer: KDE porting team <openbsd-...@googlegroups.com> WWW: https://www.kde.org/applications/education/step
