![]() ![]() ![]() 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. I like it a lot, give it a spin, it will only cost you three minutes.Here's a list of available programs for Engineers or Engineering students that are available for Ubuntu (or linux in general). It is pretty exciting, what a lot of us have been looking forward to for a long time. The Linux community support so far has been very strong, in the first week since DraftSight’s release there have been on average a little over 1,000 downloads a day. Who here isn’t a fan of the Open Design Alliance? (You can also export. But look, look!ĭraftSight has a powerful CAD interface, but can you share your files with others? Check out these SaveAs options: Most Linux programs have a barely adequate help file -I usually find Google more helpful. I was pleasantly surprised by the help file. I did miss not having an API, however this is available if you buy the premium pack. I found was that you could not change the number of columns/rows in an existing table, however this issue has been reported and a fix is expected soon. I mostly tested blocks, XREFs, layers, dimensions, tables – these are the features I usually find lacking in 2D software. The DraftSight system requirements are very modest (1 GHz x86 processor, 1GB of RAM (2GB recommended)) so my 3 GHz machine with 3 GB of RAM had no problem opening the largest DWG files I could find. I was secretly hoping it would install in my “Office” application list, but instead it went into the graphics area: Total installation time was less than three minutes. ![]() I double clicked on the download and the Ubuntu Software Center automatically took care of the rest. The installation on my Ubuntu 10.10 system was cake. The b is rather small, 68.8 Mb (I was surprised it was bigger than the Windows install – 55.5 Mb). (Who remembers trig anyway?) Now, thanks to DraftSight, I have DWG support in an interface nearly the same that I have been using since high school…all on my computer in my kitchen! QCad is a nice application, but since it doesn’t have DWG support I must admit I never used it for much more than helping my kids with their geometry homework. Until DraftSight, I mostly used “QCad” for my CAD editing software on Linux. You know I was quite excited when DraftSight for Linux was finally release last week. Free software than runs on a free operating system. ![]()
