Definition
Plain language
A research-grade spectral element solver used for computational fluid dynamics.
As stated in the literature
An open-source spectral/hp element framework for solving PDEs, used as one of two underlying solvers in the GRAFT-ATHENA scientific-computing case studies.
Why it matters: It's a credible, established solver, which makes it a meaningful target when AI-driven systems try to improve scientific-computing workflows.
For example, an aerospace researcher might use Nektar++ to simulate turbulent airflow over a wing using high-order spectral elements.
