Pyvale: The Python Validation Engine¶
Pyvale aims to become an all-in-one package for sensor uncertainty quantification simulation, experimental design, sensor placement optimisation and simulation calibration/validation. Used to simulate experimental data from an input multi-physics simulation by explicitly modelling sensors with realistic uncertainties. We are actively developing dedicated tools for simulation and uncertainty quantification of imaging sensors including digital image correlation (DIC) and infra-red thermography (IRT).
