Ubuntu for Engineers
Here's a list of available programs for Engineers or Engineering students that are available for Ubuntu (or linux in general). 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.
Matlab and Mathematica are the de facto industry standards in numerical and symbolic analysis respectively, both proprietary and non-free. Though there are many great alternatives to both of them, listed below. More info...
Mathematica - Non-free high-level computational software program used in scientific, engineering, and mathematical fields and other areas of technical computing. It uses symbolic analysis.
Matlab - Non-free high-level language and interactive environment for numerical computation, visualization, and programming. It's used for getting solutions in a fast way, with a broad online support.
Sage - A free open-source mathematics software system licensed under the GPL. It combines the power of many existing open-source packages into a common Python-based interface.
Scilab - An open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. 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. Download Scilab in the Ubuntu Software Center.

Finite element analysis
Elmer - Elmer is an open source computational tool for multi-physics problems. It has been developed by CSC in collaboration with Finnish universities, research laboratories and industry. Download Elmer in the Ubuntu Software Center.
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. More info...
Netgen - Netgen is a multi-platform automatic mesh generation tool written in C++ capable of generating meshes in two and three dimensions. Netgen has FEM-ngolve CFD-ngflow extensions. Download Netgen in the Ubuntu Software Center.
NX - NX (formerly Unigraphics) is a commercial CAD/CAM/CAE suite used in automotive, aeronautics and product design industries. It includes Design, engineering analysis (static, dynamic, electro-magnetic, thermal, using the Finite Element Method, and fluid using the finite volume method) and manufacturing. See more information in wikipedia.
OOFem - A free finite element code with object oriented architecture for solving mechanical, transport and fluid mechanics problems. 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.
Salome - A Open Source software suite including Pre-/Post processing Tools: 3D-CAD, Mesher, FEM-Software
Fluid mechanics is the branch of physics that studies fluids and the forces on them. Fluid mechanics can be divided into fluid statics, fluid kinematics and fluid dynamics. More info...
GHydraulics - It's a Quantum GIS plugin that allows to export water supply networks for analysis in EPANET. It also contains a function to calculate economic diameters based on given flowrates. The functions are accessible from the Quantum GIS plugin menu and toolbars. Download QGIS in the Ubuntu Software Center.
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 can check these examples of simulation around a cylinder and around a car.
SU2 - A free and open source suite of tools for analysis and shape design using gradient-based optimization. Includes CFD solver for both flow equations (compressible, incompressible, turbulence models, plasma) and adjoint equations on unstructured meshes. Also included are tools for mesh deformation, sliding mesh interfaces, and domain decomposition for parallel simulations. See the full list of tools for more details and the user tutorials for examples with instructions.
Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. More info...
Icarus Verilog - Icarus Verilog is a Verilog simulation and synthesis tool. It operates as a compiler, compiling source code written in Verilog (IEEE-1364) into some target format.
Computer-aided design (CAD), is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. More info...
