Aircraft Wing Finite Element Method Solver

A finite element analysis tool for aircraft wing structural optimisation with material property and geometric parameter optimisation.

Features

• Parametric 2D wing generation (birdseye)
• Orthotropic material modeling (composites). Capable of 8 noded element calculations.
• Stress minimisation using differential evolution
• Multi-core parallel processing
• ParaView-compatible VTK output, including deformed model.
• Sparsity pattern visualisation

Installation

# Clone repository
git clone https://github.com/tyecam1/AircraftWing-FEM-Solver.git
cd AircraftWing-FEM-Solver

# Create virtual environment
python -m venv venv
source venv/bin/activate  # Linux/MacOS
# OR
venv\Scripts\activate    # Windows

# Install dependencies
pip install -r requirements.txt

# Install GMSH (required for meshing)

Basic Usage
python
from wingfea import setupParams, prepMesh
from wingfea.solver import run_analysis

# Interactive parameter setup
params = setupParams()

# Run full analysis pipeline
results = run_analysis(*params)

# Save results
results['deformed_mesh'].save('wing_deformed.vtk')
Optimisation
python
from wingfea.optimisation import optimiseStress

# Run material optimisation study
optimiseStress()  # Results saved to optimisation_results.csv
