Corporate Evolution
CRF Solutions Inc. transitioned from a start‑up to a publicly traded company in 2015, following a series of successful funding rounds. The company's strategic acquisitions of mesh‑generation and post‑processing firms expanded the CRF 100 ecosystem, allowing a seamless workflow from geometry creation to result interpretation.
Key Concepts
Core Solver Architecture
The CRF 100 solver employs a modular architecture that separates the discretization engine, linear solver, preconditioner, and physics modules. This design facilitates the addition of new physical models without disrupting existing workflows. The solver is written primarily in C++ with critical sections optimized in CUDA for GPU execution.
Discretization and Grid Management
CRF 100 supports structured, unstructured, and hybrid meshes. Mesh refinement is performed using a hierarchical octree approach, enabling local resolution enhancements around boundary layers and flow separation regions. The solver automatically identifies high‑gradient zones through error estimation metrics and refines the mesh accordingly.
Turbulence Modeling
Turbulence modeling in the CRF 100 ecosystem encompasses a broad spectrum of approaches:
- Reynolds‑averaged Navier–Stokes (RANS) with standard k‑ε, k‑ω SST, and realizable k‑ε models.
- Large‑eddy simulation (LES) with dynamic Smagorinsky and WALE subgrid‑scale models.
- Hybrid RANS/LES (DES, RANS/LES blending) for moderate‑size aerospace configurations.
- Machine‑learning‑augmented turbulence closure schemes that adapt to local flow conditions.
Multiphysics Coupling
CRF 100 facilitates coupled multiphysics simulations, including:
- Thermal‑fluid interaction: conduction, radiation, and convection.
- Fluid‑structure interaction (FSI) with explicit and implicit coupling schemes.
- Electromagnetic‑fluid interaction for magnetohydrodynamic (MHD) studies.
Coupling is managed through a loose‑coupling algorithm that exchanges boundary data at discrete time steps, ensuring numerical stability while maintaining computational efficiency.
Post‑Processing and Visualization
The platform offers a built‑in visualization engine based on OpenGL, enabling real‑time rendering of velocity vectors, pressure contours, and turbulence statistics. Users can also export data in standard formats (VTK, CSV, HDF5) for external analysis with commercial or open‑source tools.
Variants and Models
