Simulation teams are under constant pressure to deliver results faster, explore more design alternatives, and support real\u2011time decision\u2011making, all without compromising accuracy. Reduced Order Model simulations (ROMs) have emerged as a powerful way to meet these demands, but they are often misunderstood.<\/h2>\n

Here, EDRMedeso specialists answer practical questions from engineers about when ROMs make sense, how they are created, and how they should be used alongside high\u2011fidelity simulations. This blog summarises the most relevant questions and answers with a focus on real engineering scenarios rather than theory.<\/p>\n

Why use a ROM if high\u2011fidelity simulations are still required?<\/strong><\/h2>\n

A common misconception is that ROMs replace high\u2011fidelity simulations entirely. In reality, ROMs are designed to complement detailed simulations \u2014 not replace them.<\/p>\n

A ROM does not require training data from the entire design space. Instead, it is built using a limited but representative set of simulation results, typically chosen to cover the boundaries and key operating conditions of the problem. This might mean training a ROM on just a handful of carefully selected simulations rather than hundreds of full model runs.<\/p>\n

Once created, the ROM can be used to:<\/p>\n
