GeomSpace is interactive geometry software for different geometric spaces. You can build your own universe of any dimension and with any geometry. You can choose Euclidean, elliptic, hyperbolic, Galilean, Minkowskii, de Sitter among other spaces.

NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. The connection to a geometry kernel allows the handling of IGES and STEP files. NETGEN contains modules for mesh optimization and hierarchical mesh refinement. Netgen is open source based on the LGPL license. It is available for Unix/Linux and Windows.

This is a collection of software modifications created to integrate NanoEngineer-1, PACKMOL and MSI2LMP for the purpose of easily creating molecular dynamics cells. NanoEngineer-1 is a molecular CAD software written by Nanorex and provides the user an easy way to create molecules, while the software modifications allow the user to type atoms using multiple force fields. PACKMOL can generate a random collection of molecules using the molecule templates from NanoEngineer-1 thus providing the...

...In the time domain generic bidirectional propagation elements, scattering elements, fractional delays, convolution with reflection functions and general z-domain networks are available and can be described using MuParserX expressions. Cylindrical and conical ducts can also be defined based on their geometry. Available models and their parameters can be enumerated and combined to form simulators for complex acoustical structures. Parameters can be specified symbolically by expressions containing other parameter values or global variables. Dependencies between parameters are resolved at run time. However, MuParserX expressions are compiled at design time. ...

The Virtual Geometry Model (VGM) provides abstract interfaces to geometry objects and functions for conversion between supported geometry formats (Geant4, Root, GDML, AGDD).

EVERT is an acoustic beam-tracing library. It is optimized for a moving listener with static geometry and sound source. It computes all the visible specular reflection paths up to the given reflection order.

ViennaTS is a C++, OpenMP-parallelized Topography simulator, focusing on processing challenges for micro- and nanoelectronics. At its core is the Level Set framework, allowing for an implicit surface description of material surfaces and interfaces. Within this framework models for geometry manipulation such as boolean operations and chemical mechanical planarization have been implemented. The tool supports several etching and deposition models, essential for the understanding of process-induced phenomena in micro- and nanoelectronics. The model support includes but is not limited to silicon etching in SF6/O2 and HBr/O2 plasmas, silicon dioxide etching in CF4 plasma, anisotropic wet etching of silicon, CFx polymer deposition on silicon, as well as several adaptable deposition models. ...

STARucn (Simulation of Transmission, Absorption and Reflection of ultracold neutrons) is a Monte-Carlo software designed to simulate experimental setups and guides for ultra cold neutrons. It relies heavily on CERN's ROOT packages. Developing team : Benoit Clément, LPSC/UJF Damien Roulier, ILL/UJF

...CAPLET can directly handle GDS2 layout files into capacitance matrices in both GUI and command line interfaces. The internal extraction algorithm is specialized for VLSI interconnect structures but not exclusively, as long as the structure is of Manhattan geometry and embedded in a uniform dielectric material.

The goal of project "defE" is to build a library to handle the simulation of the transformation and collision about deformable geometry using the sphere-spring system. It uses CUDA to deal with the enormous mount of parallel computable calculation.

OpenPT is a software framework for developing applications that solve particle transport problems, including fully-featured deterministic and stochastic transport algorithms, cross section library generation, and depletion and activation methods.

Geometric modeling, mesh generation and definition of boundary conditions for the numerical solution PDE problems by finite element and finite volume methods.

Matho is a OS Independant Application and API for mathematical operations, features include curve sketching, calculus, iterative formulae, algebra solver, 2d/3d geometry and mechanical and statistical functionality.
