Computational engineering

Computational engineering is an exciting and growing field that uses computers to help solve big engineering problems. It is different from computer engineering, even though they sound similar. In computational engineering, engineers create special computer programs called computational models. These models use math and logic to understand and solve engineering challenges.

Engineers put their knowledge into these computer programs, which then create many different design options based on what is needed. These designs can be tested and improved using more math models and feedback loops. This helps engineers find the best solutions without building everything in real life first.

Computational engineering also uses simulations of physical behaviors and high-performance computing to study complex problems in engineering and even natural phenomena. It is closely related to Computational Science and Engineering, which is often called the "third mode of discovery" along with theory and experimentation. By using computer simulations, engineers can test ideas that would be too expensive or difficult to try in the real world.

While computational engineering uses ideas from computer science, it is not the same. It focuses on applying these ideas to real engineering problems, making it a valuable tool in many industries.

Methods

Computational engineering uses special methods and tools to help solve difficult engineering problems. These include modeling and simulation to test ideas, algorithms to find solutions, and ways to analyze and show data clearly. Important math areas like linear algebra and optimization are also used.

Computers and programming are key in computational engineering. Languages like FORTRAN, C++, and Python are often used. Tools such as MATLAB help make quick progress on new projects and check models. Data science helps handle big sets of information and find useful patterns.

Open source

There are several free and open-source tools that help with computational engineering. OpenSCAD was released in 2010 and lets users create 3D models through scripts. CadQuery uses Python to build 3D models and is based on the OpenCascade framework. It is available under the Apache License. Another tool, PicoGK, is an open-source framework for computational engineering, also released under the Apache License.

Applications

Computational engineering is used in many different fields to help solve complex problems. In aerospace engineering and mechanical engineering, it helps design safer aircraft and cars through simulations. It is also used in biology and medicine to understand how the human body works and to develop new treatments.

Other areas include chemistry for studying molecules, civil engineering for building stronger structures, and environmental engineering for predicting weather and climate changes. Computational engineering plays a role in many industries, helping engineers make better decisions through computer models and simulations.

Software

Computational engineering uses computer programs to help solve big engineering problems. Engineers put their knowledge into these programs, creating tools that can create many different design options based on what is needed. These programs often use smart algorithms to simulate real-world situations, helping engineers make better decisions.

This field combines computer science with engineering, making it easier to design everything from buildings to machines by testing ideas quickly on a computer before building them in real life.
