Optimize flow, structure, and loads with validated evidence you can trust.
Numerical Simulations, CFD, FEM, FSI and Loads
Competence.
CFD for pressure loss, heat transfer, and external aerodynamics, FEM for strength, stiffness, and dynamic behavior, coupled where needed for FSI and aircraft load cases. Expect physics that match reality, clear limits, and design guidance before anything is manufactured.
Our Workflow
Define Objectives and Acceptance Criteria
Pin down the physics, operating points, and decision metrics. Set target errors, convergence tolerances, and what “good enough” means.
Geometry Prep and Meshing Strategy
Clean and defeature CAD, seal fluid domains, define contact and symmetry. Plan mesh type and resolution, y⁺ targets, growth rates, and grid-independence checks.
Baseline Simulations and Sanity Checks
Run a first, stable baseline. Verify residuals, mass and energy conservation, force balances, and compare against correlations or simple models.
Design Space Exploration and Sensitivity
Sweep key parameters or run a DOE. Use response surfaces or adjoint/sensitivity analysis to see which variables move the metrics.
Coupled Analysis and Loads Extraction
Couple CFD and FEM (loose or strong) where needed. Extract load envelopes, modal participation, stiffness/pressure interactions, and flight-condition loads.
Correlation and Recommendations
Compare predictions to test or field data, quantify error and uncertainty, document limits. Translate findings into clear design actions and risk impacts.
