Mechanical engineering: computer-aided engineering

Computer-aided engineering (CAE) uses computational simulation instead of physical or mathematical modelling to solve engineering problems. CAE plays a role in the vast majority of engineering enterprises. It can show if something behaves in a way that would be cost-prohibitive, time-consuming or just too dangerous to try. The ability to model complex parts, machinery and environments on a computer sounds fantastic. However, the answers obtained are only as good as the engineer who made and ran the model – that is where this module comes in.

Modules count towards OU qualifications

OU qualifications are modular in structure; the credits from this undergraduate module could count towards a certificate of higher education, diploma of higher education, foundation degree or honours degree.

Credits

Credits

  • Credits measure the student workload required for the successful completion of a module or qualification.
  • One credit represents about 10 hours of study over the duration of the course.
  • You are awarded credits after you have successfully completed a module.
  • For example, if you study a 60-credit module and successfully pass it, you will be awarded 60 credits.

Study level

Across the UK, there are two parallel frameworks for higher education qualifications, the Framework for Higher Education Qualifications in England, Northern Ireland and Wales (FHEQ) and the Scottish Credit and Qualifications Framework (SCQF). These define a hierarchy of levels and describe the achievement expected at each level. The information provided shows how OU module levels correspond to these frameworks.

What you will study

Mechanical engineering: computer-aided engineering (T329) introduces and develops an understanding of the typical three elements included in CAE (computer-aided engineering):

  • finite element analysis (FEA)
  • multibody dynamics (MBD)
  • computational fluid dynamics (CFD).

All run from a single software package: ANSYS Workbench.

The module comprises three parts, each concentrating on a different CAE element:

Part 1: Computer-aided design and finite element analysis
This part begins with a slight detour in the form of an introduction to computer-aided design. This short foray will show you how models are drawn and assembled before they can be analysed using any of the tools. You’ll then move on to analysing these models using the finite element part of the software package, allowing you to discover how these models would behave in different scenarios. There is then a theoretical section so you understand what the software is doing and how it does it, which will provide a solid foundation for interpreting problems and results. Validating results in one way or another is vital for using any modelling with confidence. So, towards the end of this section, you’ll 3D-print a part you designed and test it to see if it behaves as your model predicts.

Part 2: Mechanisms and multibody dynamics
In this part, you’ll learn about mechanisms in engineering and how to model them – both analytically and computationally through the multibody dynamics (MBD) functionality in ANSYS. You’ll begin by examining some simple, familiar systems made from simple joints and exploring their behaviour through the MBD software. The module then introduces kinematic analysis, allowing these simpler systems’ displacement and velocity to be analysed and compared to the results from the MBD. It then tackles more complicated situations that would be impractical to solve by hand. Finally, you’ll move on to gears, belts and pulleys and how they interact with the systems containing them.

Part 3: Computational fluid dynamics
The third part introduces the computational fluid dynamics (CFD) package in ANSYS. It begins with a general overview of the technique with many application examples of CFD. You’ll learn the fundamentals behind CFD programs and about fluid flow more generally, including the Navier–Stokes equations. Following this, you’ll focus on the flow around wind turbines, paying particular attention to boundary layers. You’ll then move on to considering oscillatory flow, vortex shedding and compressibility. During this part, you’ll also have the chance to control a wind tunnel to compare a physical model with the virtual one in the software.

You will learn

You’ll learn how CAE software works and what it can do, along with its limitations, assumptions and how to validate the output.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

Assessment

The assessment details for this module can be found in the facts box.

Future availability

Mechanical engineering: computer-aided engineering (T329) starts once a year – in October.

This page describes the module that will start in October 2025.

We expect it to start for the last time in October 2029.

Regulations

As a student of The Open University, you should be aware of the content of the academic regulations which are available on our Student Policies and Regulations website.

Course work includes:

2 Tutor-marked assignments (TMAs)
3 Interactive computer-marked assignments (iCMAs)
End-of-module assessment


Entry requirements

T329 has no formal entry requirements; however, it is an OU level 3 module. Therefore, you need a good knowledge of engineering obtained through OU level 1 and 2 study or another higher education institution.

Can you study an Access module for free?

Depending on eligibility and availability of places, you could apply to study your Access module for free.

To qualify, you must:

  1. be resident in England
  2. have a household income of not more than £25,000 (or be in receipt of a qualifying benefit)
  3. have not completed one year or more on any full-time undergraduate programme at FHEQ level 4 or above or successfully completed 30 credits or more of OU study within the last 10 years

How to apply to study an Access module for free

Once you've started the registration process, either online or over the phone, we'll contact you about your payment options. This will include instructions on how you can apply to study for free if you are eligible and funded places are still available.

If you're unsure if you meet the criteria to study for free, you can check with one of our friendly advisers on +44 (0)300 303 0069, or you can request a call back.
