QuickField Builders

A free tool that converts JSON metafiles into native QuickField files — it doesn't depend on AI, and can also be used in regular automation workflows.

QuickField Builders is a set of free tools for converting human-readable JSON metafiles into native QuickField files.

The Builders themselves have nothing to do with artificial intelligence — AI is just one possible source of the JSON metafiles. The same tools can also be used with hand-written files, custom scripts, external engineering applications, or enterprise engineering systems that aren't well suited to creating QuickField problems by hand.

Builders need to run on the same computer as an installed copy of QuickField, and control QuickField through the ActiveField API. Any edition of QuickField can act as the COM server, but only QuickField Professional has no built-in mesh size limit.

Why JSON Metafiles

QuickField Builders use three types of JSON metafile:

.qfpProblem definition

.qfsGeometric model

.qfdMaterials, field sources and boundary conditions

These metafiles give a compact, readable description of the simulation problem.

Compared with writing API scripts directly, JSON metafiles are easier to review, edit, put under version control, generate automatically, and exchange between different software tools.

Reviewing generated API code requires a detailed understanding of the simulation software's API; reviewing a JSON metafile is closer to reviewing the engineering model itself — geometry, materials, field sources, boundary conditions and problem settings. That's what makes JSON metafiles suited both to AI-assisted modeling and to traditional automation workflows.

The Three Builders

Problem BuilderCreates a complete QuickField problem from .qfp, .qfs and .qfd metafiles: it sets up the problem database, generates the required model and data files, establishes the references between them, and can optionally start solving automatically. Problem Builder already includes Model Builder and Data Builder — if you plan to use AI to generate a complete QuickField problem, Problem Builder alone is usually all you need.

Model BuilderConverts a .qfs metafile into a QuickField geometric model. It's included in Problem Builder, but can also be used on its own when only the geometry needs to be generated.

Data BuilderConverts a .qfd metafile into a QuickField data file containing material properties, field sources and boundary conditions. It's included in Problem Builder, but can also be used on its own when only the data needs to be generated.
