You can check these examples of simulation around a cylinder and around a car. OpenFOAM - A free, open source CFD software package to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics. You will need to contact them to get it, but as seen here, they have Linux support. Download QGIS in the Ubuntu Software Center.įluent - Modelling of flow, turbulence, heat transfer, and reactions for industrial application. The functions are accessible from the Quantum GIS plugin menu and toolbars. It also contains a function to calculate economic diameters based on given flowrates. GHydraulics - It's a Quantum GIS plugin that allows to export water supply networks for analysis in EPANET. Fluid mechanics can be divided into fluid statics, fluid kinematics and fluid dynamics. Salome - A Open Source software suite including Pre-/Post processing Tools: 3D-CAD, Mesher, FEM-Softwareįluid mechanics is the branch of physics that studies fluids and the forces on them. The aim of this project is to provide efficient and robust tool for FEM computations as well as to offer highly modular and extensible environment for development. OOFem - A free finite element code with object oriented architecture for solving mechanical, transport and fluid mechanics problems. It includes Design, engineering analysis (static, dynamic, electro-magnetic, thermal, using the Finite Element Method, and fluid using the finite volume method) and manufacturing. NX - NX (formerly Unigraphics) is a commercial CAD/CAM/CAE suite used in automotive, aeronautics and product design industries. Download Netgen in the Ubuntu Software Center. Netgen has FEM-ngolve CFD-ngflow extensions. Netgen - Netgen is a multi-platform automatic mesh generation tool written in C++ capable of generating meshes in two and three dimensions. Download Gmsh in the Ubuntu Software Center. Gmsh - An automatic 3D finite element grid generator with a built-in CAD engine and FEM post-processor. The finite element method (FEM) is a numerical technique for finding approximate solutions to partial differential equations (PDE) and their systems, as well as (less often) integral equations. Download Elmer in the Ubuntu Software Center. It has been developed by CSC in collaboration with Finnish universities, research laboratories and industry. Download Scilab in the Ubuntu Software Center.Ī list with more alternatives can be found here.Įlmer - Elmer is an open source computational tool for multi-physics problems. It can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and modeling, simulation of explicit and implicit dynamical systems and (if the corresponding toolbox is installed) symbolic manipulations. Scilab - An open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. It combines the power of many existing open-source packages into a common Python-based interface. Sage - A free open-source mathematics software system licensed under the GPL. Downlaod GNU Octave in the Ubuntu Software Center. Octave - GNU Octave is a FOSS high-level interpreted language, primarily intended for numerical computations of linear and nonlinear problems. It's used for getting solutions in a fast way, with a broad online support. Matlab - Non-free high-level language and interactive environment for numerical computation, visualization, and programming. Mathematica - Non-free high-level computational software program used in scientific, engineering, and mathematical fields and other areas of technical computing. Though there are many great alternatives to both of them, listed below. Matlab and Mathematica are the de facto industry standards in numerical and symbolic analysis respectively, both proprietary and non-free. Not all of them are in the official repositories, not all of them are free and open, but they can be used on a daily basis to improve the workflow of any Engineer. Here's a list of available programs for Engineers or Engineering students that are available for Ubuntu (or linux in general).
