1Dmodeller

1Dmodeller is a software package designed for creating, analyzing, and simulating one-dimensional models. It is used across disciplines such as physics, engineering, geoscience, and data analysis to work with one-dimensional profiles, signals, and distributions. The design emphasizes rapid model prototyping and clear visualization of results.

Key capabilities include import of 1D data (CSV, TSV, or plain text), model definition with parameters, and access to numerical solvers for 1D problems such as diffusion, transport, and reaction kinetics. The system provides 1D plotting, multi-curve comparison, residual analysis, and curve fitting using least-squares or probabilistic methods. It also supports scripting for custom models and batch processing to promote reproducible workflows.

Typical workflows involve loading data, specifying a model and constraints, selecting a solver and boundary conditions, running simulations, and visualizing outputs. Users can fit model outputs to data, estimate parameters, and quantify uncertainty. Results can be exported as CSV files, images, or embedded into reports.

The architecture centers on a core numerical engine that handles 1D arrays and time stepping, a modular library of models, and a visualization layer. An extensible plugin system allows developers to add new solvers, data readers, and plotting tools. The interface is designed to be cross-platform and scriptable to integrate with other analysis pipelines.

Applications include material science studies of diffusion and thin-film profiles, geophysical profiling, sensor data analysis, and education in one-dimensional modeling methods. The project aims to provide a transparent, reproducible environment for exploring simple to moderately complex 1D systems.
