The roots of this discipline can be traced back to the mid-20th century, evolving hand-in-hand with the development of computers. From the colossal, room-filling machines of the 1940s to the sophisticated, super-fast computers of today, the growth of computational power has propelled the field to new heights, making what was once thought impossible, possible.

In modern times, computational engineering has become indispensable. It’s shaping our future, driving innovations in sectors like aerospace, bioengineering, and renewable energy. Computational engineering is pushing boundaries, sparking innovation, and solving the problems of tomorrow and today.

In this blog post, we’re going to explore the incredible applications of computational engineering across various industries. We’ll also look at some groundbreaking innovations that have left a mark on the world so we can appreciate their significance in steering us toward a more innovative, efficient, and sustainable future.

Fundamentals of Computational Engineering

Computational engineering is formed on a solid foundation of mathematical and scientific principles. It’s a multidisciplinary field that combines elements from mathematics, physics, computer science, and engineering to solve complex problems using computer simulation techniques. Here are the fundamentals::

Mathematics in Computational Engineering

A significant part of computational engineering involves complex mathematics. Mathematics is the universal language of engineering, and in the realm of computational engineering, it’s indispensable. When we talk about predicting weather patterns or carrying out wastewater treatment plant design calculations, we are discussing complex mathematical equations and models. These computational models help us understand and simulate real-world phenomena with amazing accuracy.

Computer Science Foundations

Computer science gives us the tools and languages to write efficient code, manage large data sets, and exploit the capabilities of modern computers to their fullest. One of the fascinating aspects of computational engineering is its relationship with computer science, especially in areas like machine learning and high-performance computing. Emerging research showcases how leveraging machine learning can enhance decision-making and improve water resource management strategies.

Integration of Engineering Principles

Lastly, the integration of engineering principles is what brings computational science and engineering to life. It’s not simply about having the mathematical models and computing power; it’s about applying these in a way that’s relevant to real-world engineering problems. This means understanding the nuances of different engineering disciplines, whether it’s the science behind wastewater management or the best sustainable engineering practices for power utilities.

Computational Modeling Techniques

Computational modeling techniques are the cornerstone of computational engineering, offering the essential tools to break down complex phenomena into comprehensible and solvable problems.

Finite Element Analysis (FEA)

Finite Element Analysis (FEA) represents a pivotal computational method extensively utilized across the engineering sector to forecast product responses to various real-world phenomena, including forces, vibrations, thermal changes, and fluid dynamics. This mechanical engineering technique simplifies complex issues by segmenting them into smaller, more manageable finite elements. Consequently, FEA empowers engineers to pinpoint and address potential design flaws before the start of manufacturing, thereby conserving both time and resources.

Computational Fluid Dynamics (CFD)

Computational Fluid Dynamics, or CFD, includes using math and computer algorithms to figure out how fluids flow. It’s an innovative tool that engineers and scientists use to see how liquids and gasses behave under different conditions. Computational engineers use it to help design and improve different structures, from planes and cars to environmental projects.

Discrete Element Method (DEM)

The Discrete Element Method (DEM) is a sophisticated computational technique designed for simulating the dynamics and interactions of numerous small particles. Diverging from continuum approaches such as Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD), DEM zeroes in on individual phases or particles. This makes it exceptionally suitable for modeling granular materials, rock mechanics, and powder processing scenarios. DEM enables computational engineers to accurately forecast the behaviors of solid particles, capturing details of collisions, energy dissipation, and aggregation processes with remarkable precision.

Molecular Dynamics (MD)

Molecular Dynamics (MD) serves as a simulation technique within the spaces of physics and chemistry, designed to explore the intricate movements of atoms and molecules. This method enables detailed observation of how atoms and molecules move over time, shedding light on the structural, dynamic, and thermodynamic characteristics of materials at the molecular scale. MD simulations play a vital role in fields such as materials science, biophysics, and drug discovery, providing a detailed microscopic perspective on molecular interactions and processes.

Multiscale Modeling

Multiscale modeling represents a computational strategy designed to simultaneously bridge diverse spatial and temporal scales, which addresses complex challenges that defy resolution at a single scale. This technique proves especially potent in the space of materials science. Here, characteristics at the nano or microscale can profoundly influence the behavior observed at the macroscale. Through the integration of various physical models across different levels, multiscale advanced modeling delivers a holistic understanding of phenomena, encompassing everything from atomic interactions to the behavior of materials on a grand scale.

Software Tools in Computational Engineering

Simulation software serves as the backbone of computational engineering, providing a platform for professionals to create virtual models of engineering projects. These digital environments enable the analysis of the behavior and performance of designs under simulated real-world conditions. This capability is a must across various stages of project development, from initial design to final validation, ensuring that potential issues are identified and addressed early in the process.

Industry-leading Software Packages

The Transcend Design Generator (TDG) exemplifies the practical application of computational engineering in the spaces of wastewater treatment and substation design. By combining a simple yet powerful user interface with advanced process design simulations, TDG democratizes the design process, enabling both novices and seasoned experts to generate comprehensive preliminary designs. Inputs begin with straightforward parameters, undergo rigorous data science validation based on universal design principles, and may include specialized inputs for tailored solutions. Through dynamic and steady-state modeling, TDG produces detailed simulations that inform the selection of equipment and the creation of engineering documentation. This seamless integration of computational techniques facilitates efficient, accurate, and customizable design outputs, embodying the essence of computational engineering by marrying theoretical models with real-world engineering applications.

Open-source Alternatives

While industry-leading packages like TDG offer comprehensive solutions, the open-source community also provides a wealth of resources for those looking to access simulation tools at no cost. Open-source alternatives include:

  • OpenFOAM – a free, open-source computational fluid dynamics software package with a wide range of features and capabilities.
  • LIGGGHTS – an open-source discrete element method simulation tool for granular materials and complex fluids.
  • LAMMPS – a molecular dynamics simulation tool that can simulate a wide range of materials and phenomena at the atomistic scale.

They often foster innovation and collaboration, allowing users to customize and improve the software to meet the specific needs of their projects. These alternatives are beneficial for educational purposes, small-scale projects, or for those just beginning to explore the field of computational engineering.
