FEA & CFD Project Consulting
Simulation-driven engineering you can defend.
DeCaire Dynamics provides finite element analysis and computational fluid dynamics for product development, design verification and failure investigation, delivered with documented assumptions and results your team can review.
Led by an aerospace engineer whose experience includes lunar space power, aircraft engine sensors and fighter jet fuel system components. Meet Camren
Services
Analysis that answers the engineering question.
Every project starts with the decision you need to make. The model, the mesh and the report are built to support that decision. Nothing more, nothing less.
See project examplesStructural FEA
Stress, deflection, contact and margins of safety for aerospace hardware, pressurized housings, valves, brackets, weldments and skids, always backed by hand calculations.
Computational Fluid Dynamics
Internal and external flow, pressure drop, flow distribution and aerodynamic loads for valves, manifolds, pumps and ducts.
Compressible Flow
Gas-system flow rates, choked flow, orifice and valve sizing, and safety assessment for hydrogen, oxygen, nitrogen and air systems.
Thermal Management
Heat rejection and heat recovery strategies, conduction and convection modeling, heat exchanger sizing and thermal stress.
Vibration & Fatigue
Modal, sine, random vibration and shock response, with cyclic fatigue and endurance life assessment for components in harsh environments.
Electromagnetic Simulation
Permanent magnet and magnetic circuit modeling for sensors, chip detectors and actuators.
Qualification Plans
Test plans and procedures for DO-160G and MIL-STD-810
We prepare qualification plans, acceptance test procedures and environmental stress screening documentation based on your product requirements and applicable standards.
We document the test setup, conditions and pass criteria so your chosen lab can run the tests and your team can review the results.
Discuss your test planEnvironmental test procedures
- Vibration (sine & random)
- Operational & crash-safety shock
- Thermal cycling & thermal shock
- Altitude & decompression
- Temperature–vacuum
- Accelerated aging
Production & durability procedures
- Environmental stress screening (ESS)
- Acceptance test procedures (ATP)
- Pressure cycling, proof & burst
- Cyclic fatigue & endurance
- Fluid & fuel compatibility
- Cryogenic & high-temperature
Engineering Documentation
The paperwork that gets hardware approved
Aerospace programs run on documentation as much as on hardware. We prepare the reports, analyses and checklists that OEMs, prime contractors and the FAA expect, in the formats they expect.
Qualification & compliance
- Qualification test procedures & reports
- Requirements compliance matrices
- Qualification-by-similarity analysis reports (QSAR)
Risk & reliability
- Failure modes & effects analysis (FMEA)
- Design FMEA (DFMEA)
- Failure investigation reports
Certification & production
- FAA 36-item checklists
- Weight & center-of-gravity reports
- Assembly instructions
- Stress reports with full hand calculations
How We Work
A documented, repeatable process
Step 1
Scope & proposal
We define the load cases, boundary conditions, materials and acceptance criteria with you, then provide a fixed-scope proposal.
Step 2
Model & verify
Models are checked against hand calculations and mesh convergence studies before any result is reported.
Step 3
Report & recommend
You receive a clear report with assumptions, results, margins and practical design recommendations.
Selected Work
From mesh to decision

Pressure-surge loading of a fuel-system valve body.
Valve CFD
Jet, recirculation and pressure drop through a globe valve.
Unsteady CFD
