SU2

Config-and-mesh-driven CFD for aerodynamic, incompressible, compressible, thermal, and elasticity workflows.

Coverage

External aerodynamics, compressible RANS and Euler, incompressible flow, heat transfer, and structural elasticity. Application routing comes from typed physics (regime, dimensionality, compressibility) in the CaseSpec.

The .cfg file

The adapter writes a single *.cfg (with MARKER_* declarations) and an SU2-format mesh. The cfg structure is auto-generated from CaseSpec controls — solver type, time discretization, convective scheme, turbulence model, output frequency.

Marker tags must match

Boundary conditions reference mesh marker tags by name (MARKER_INLET, MARKER_OUTLET, MARKER_HEATFLUX, MARKER_ISOTHERMAL, MARKER_SYM). The adapter enforces that every BC has a matching marker; a missing marker is a typed validation error, not a runtime crash.

Coefficient monitoring

Drag, lift, side-force, moment, and surface heat-flux coefficients are declared in the cfg and tailed by the SU2 parser. The platform binds each into a typed QoI with units and tolerance.

Benchmark validation

The SU2 resource pack ships the project's tutorial and test cases as local references. Standards-pack-aware validation (e.g., NAFEMS aerodynamics) is supported when the CaseSpec selects a matching pack.
