Fluids Solver Software Engineer

United States, RI, Johnston

Role Description & Responsibilities

The SIMULIA Fluids organization has a unique array of technologies that covers a wide range of flow regimes. These include state-of-the-art finite volume methods on unstructured body-fitted meshes and industry-leading lattice Boltzmann technology on Cartesian refined meshes. We continue to develop core technologies as we integrate them into our 3DEXPERIENCE platform for unified design and simulation.

We are seeking a Fluids Solver Software Engineer with a strong background in computational fluid dynamics, parallel processing and C++ programming to join us during these exciting times.

  • Implement new physics capabilities to meet the demands of tomorrow's industry.
  • Improve our ability to handle very large customer models (hundreds of millions of elements)
  • Follow sound software engineering practices. The code we write today will underpin our platform simulation products for years to come – it needs to be maintainable, extensible and robust.
