Making it real, making it digital: how to combine marine structural analysis with real-world data

By Elspeth Mosedale

Here at Simcenter we talk a lot about the digital twin, a virtual representation of a real-world object. If we are performing marine structural analysis, a digital twin gives us the ability to test ‘what if’ scenarios and try out many options in a virtual world before finalizing the design and starting to build. But we need to remember that this virtual structure does not exist on its own: it interacts with, and is affected by, the wider world around it.

In marine design, the real-world object is of course a ship, a complex structure affected by complex external conditions such as waves. Predicting how this structure will respond to these conditions is a vital part of the design process: vessel certification depends on fulfilling strict criteria to ensure safety and stability.

A ship interacting with waves: how can we ensure structural stability under all operating conditions?

You can use structural analysis tools such as Simcenter 3D to create a digital twin of the vessel, and predict its response in a wide range of structural scenarios. But how can we be certain that this digital twin is realistic? That the responses it predicts are real-world responses?

The answer lies in using real-world data to define and validate the initial virtual model.  In this on-demand webinar we take a look at how to combine real-world test data with a structural model in Simcenter 3D, and why this is important in creating a true digital twin. Our speakers cover:

  • How test data increases the realism of your marine structural analysis and gives confidence in your predictions
  • Methods for gathering real-world test data for vessels
  • Examples of vessel structure simulations
