Fieldmodeller

Fieldmodeller is a software toolkit designed to create, manipulate, and analyze spatial fields, including scalar fields such as temperature or potential, and vector fields such as velocity or magnetic flux density. It provides an abstraction for representing fields on discrete grids or meshes and offers operations for field generation, interpolation, and visualization.

The core capabilities typically include grid generation, field creation from analytic expressions or experimental and simulation data, numerical operations such as gradient, divergence, curl, and Laplacian, and the ability to apply boundary conditions and solve partial differential equations (PDEs) including Poisson, diffusion, and Maxwell-type equations. It often supports time-dependent simulations to evolve fields and offers various solvers (implicit and explicit) with convergence controls.

Input and output functionalities cover data in formats such as CSV, NetCDF, VTK, or custom formats; the toolkit can export field maps, meshes, and derived quantities. It usually provides scripting interfaces (Python, C++) and, in many implementations, graphical user interfaces for visualization and exploration.

Applications and users span electromagnetics, acoustics, fluid dynamics, geophysics, climate science, and education. Fieldmodeller is used by researchers, engineers, and instructors to study field behavior, verify models, and illustrate physical concepts, supporting reproducible workflows and teaching demonstrations.

Limitations and design considerations include that accuracy depends on discretization and numerical methods, with potential errors near boundaries. Performance scales with grid size and solver complexity, and users must supply appropriate boundary conditions, validation data, and domain knowledge to build meaningful models.
