Easy to use 3D truss analyzer using finite element methods.

This application is intended to be a tool for easy, almost automatic, creation and calculation of gear transmission finite element models. It consists of a geometry and mesh generator based on GMSH and a finite element model based on GETFEM++.

Program was created for optimized packing of two dimensional rectangular elements at orthogonal table with main purpose of printing cutting sheets that can be used for cutting material at production in wood and panel furniture manufacturing. It is developed upon authors several years of experience at woodworking, and actual carpenters needs when such software is in question. In spite its look it is fully functional peace of software , with all necessary elements needed for generating cutting sheets. GUI is simple and it consists of fields for entering table and element dimensions on the right. Packing, optimization, cutting and cleaning table edges section bottom left and statistic section bottom right. Upper left are table description field and cut sheet drawing at the center. Right click at the cut sheet drawing and there are printing options. NOTICE : This program was not created for sellers of chipboard and other board materials. All the best, Author

Advanced Simulation Library (ASL) is a free and open source multiphysics simulation software package. Its computational engine is based, among others, on the Lattice Boltzmann Methods (http://en.wikipedia.org/wiki/Lattice_Boltzmann_methods) and is written in OpenCL (http://en.wikipedia.org/wiki/OpenCL) which enable extraordinarily efficient deployment (http://asl.org.il/benchmarks) on a variety of massively parallel architectures, ranging from inexpensive FPGAs, DSPs and GPUs up to heterogeneous clusters and supercomputers. The engine is hidden entirely behind C++ classes, so that no OpenCL knowledge is required from application programmers. ASL can be utilized to model various coupled physical and chemical phenomena and employed in a multitude of fields: computational fluid dynamics, virtual sensing, industrial process data validation and reconciliation, image-guided surgery, computer-aided engineering, high-performance scientific computing, etc..

This plugin enable unsupported functionalities for Autodesk Inventor 2014 and above. Autodesk doesn't support Autorun macros for VBA projects anymore, but with this plugin it is still possible to use the commands "AutoOpen", "AutoEdit", "AutoSave", "AutoClose" and "AutoNew" subroutines stored within "Thisdocument" module.

The Brick Work Quantity Estimator is a software tool used to estimate the quantity of Brick, Cement and Sand required for building projects. It is designed with a feature to input data like brick and wall size in various unit systems.

FEDES is a Finite Element Data Exchange System for mapping finite element analysis data between different FE solvers and meshes with different element types and densities. Six commercial FE solvers are supported (ABAQUS, ANSYS, DEFORM, MARC, MORFEO, VULCAN). The FEA data outputted can be visualized with the open source program ParaView.

Fachwerk3D calculates three-dimensional strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

The developed graphical interface is based on the SKILL language which is a Lisp dialect used as a scripting language and PCell (Parameterized Cells) description language used in many EDA software suites by Cadence Design Systems.

Library to manage DXF file Format.

This Application assists the usage for CNC threading, especially the Mach3 software. The threading cycle uses the G76 command with some parameters. This program lets the user select from hundreds of predefined or free definable thread standards and calculates the parameters for the Mach3 command line. So, essentially just select your thread, calculate it, copy & paste the result to a GCode file, hit "Cycle start" and you get exactly what you want. Also included is a little tool to calculate the pitch diameter of a thread based on a measurement with three wires. Supports the threading standards M, G, R, BSW, BSF, UNC, UNF, UNEF and tapered Pipe R/Rc and Metrical threads. New: NPSM, NPT, NPTF, NPSC, NPSF. Includes an improved version of the Mach3 M1076.m1s threading macro and a matching screenset. Try also the Feed Calculator: www.sourceforge.net/p/feedcalculator

Create Strain and Kinetic Energy Density maps out of a Natural Frequency extraction analysis (i.e. modal analysis). Works with a variety of FEA results format: NASTRAN, ABAQUS, Ansys, Medina/Permas.

QroCAD is a beginner-friendly CAD software available for both web and desktop.

Ce programme est une aide au dessin pour produire les profils Ligne aérienne Haute Tension à partir des éléments techniques de PLSCADD. Ce programme génère les profils sous AutoCAD pour répondre à la charte graphique spécifique du gestionnaire de réseau : RTE-France.

This project is a simple launcher for nanoCAD 5.0 which will start an instance nanoCAD 5.0, automatically close the welcome screen and can be used to open existing documents with nanoCAD 5.0. No installation is required, just download, save wherever you like and run it. Note: Since nanoCAD is a "MDI" application, this launcher start only one instance of nanoCAD.
