This is the intro before the intro!

This is the course that design, project, and test engineers, and even managers should take as a first step toward engineering simulation democratisation. This course will empower the non-specialist to understand the value and purpose of up-front engineering simulation and optimise its implementation in analysis-driven design.

More and more, engineering simulation is being geared toward design engineers for initial sizing, configuration, and other decisions at the concept stage. The idea is to minimise the cost of design and development by avoiding costly corrections later in the development process as well as time-consuming back and forth between the design engineer and engineering analyst.

However, engineering simulation is only as good as the user’s understanding of it. In this course, the non-specialist will learn the fundamentals necessary for understanding simulation's role in the design process.

Vital information includes:

  • Overview of engineering simulation, including its value, types of simulation, and its challenges
  • Qualitative overview of simulation technology and basic modelling workflow
  • Detailed breakdown of each of the steps in simulation modelling workflow along with recommendations and tips
  • Results interpretation and sources of error
  • Verification and validation

Throughout the course, the students will be engaged and challenged through a number of in-session exercises. This interaction between the students and instructor will solidify the students’ understanding of the material and accelerate their adoption of an engineering analysis mindset.
