RB-FEA: THE GOLD STANDARD FOR PHYSICS-BASED MODELING OF INDUSTRIAL-SCALE EQUIPMENT

A technical deep dive from Akselos Chief Scientific Officer Dr. David Knezevic on how RB-FEA runs system-level structural analysis at the speed of operations, with a certified accuracy check on every solve.

In this exclusive white paper, you’ll learn:

  • How RB-FEA solves the same governing equations as FEA on a reduced basis, and returns an accuracy indicator with every solution
  • How component-based training scales structural twins past 100 million degrees of freedom without a single full-system solve
  • How Adaptive Reduced-Order-Model Enrichment (ARE) keeps every model within a specified tolerance throughout its operating life
  • How the Hybrid Solver combines RB-FEA and full-order FEA in one model for localized plasticity and contact

KEY TAKEAWAYS FROM THE WHITE PAPER

Every RB-FEA solution comes with a computable accuracy indicator. Results can be post-processed, code-checked, and reported with the same procedures and standards engineers already apply to FEA.

RB-FEA trains component by component, with no full-system solve. A complete steam methane reformer model reaches the equivalent of more than 100 million FEA degrees of freedom.

Every solve in operation is checked against a specified tolerance. When Solve 154 exceeded it, ARE automatically enriched the model in the cloud and the re-solve came back within tolerance, at an accuracy indicator of 9.9×10⁻⁴.

A dent or crack found at inspection is added by swapping in the affected component, with no retraining of the rest of the model. Operators see the defect’s effect on the entire structure within minutes rather than days.
