QuickField Builders

QuickField Builders are free utilities that convert human-readable JSON metafiles into native QuickField files.

Builders are independent of Artificial Intelligence. AI is only one possible source of the JSON metafiles. The same tools can be used with manually prepared files, custom scripts, external engineering applications, or corporate engineering systems where direct manual creation of QuickField problems is not optimal.

Builders work with QuickField installed on the same computer and control QuickField through the ActiveField API. Any QuickField edition may be used as a COM server, but only QuickField Professional Edition does not have built-in mesh size limits.

Why JSON Metafiles?

The QuickField Builders use three JSON metafile types:

• .qfp — problem definition;
• .qfs — geometry model;
• .qfd — materials, sources, and boundary conditions.

These metafiles provide a compact, human-readable description of the simulation problem.

Compared with direct API scripting, JSON metafiles are easier to review, edit, store under version control, generate automatically, and exchange between different software tools.

Checking generated API code requires detailed knowledge of the simulation product API. Checking JSON metafiles is closer to reviewing the engineering model itself: geometry, materials, sources, boundary conditions, and problem settings.

Because of this, JSON metafiles work well both for AI-assisted model generation and for traditional automation workflows.

Problem Builder

Problem Builder creates complete QuickField problems from .qfp, .qfs, and .qfd metafiles.

It creates the problem database, generates the required model and data files, establishes the references between them, and can optionally start the solution process automatically.

Problem Builder includes Model Builder and Data Builder. If you plan to generate complete QuickField problems using AI, only Problem Builder is normally required.

Model Builder

Model Builder converts .qfs metafiles into QuickField geometry models.

It is included in Problem Builder but may also be used separately when only geometry generation is required.

Data Builder

Data Builder converts .qfd metafiles into QuickField data files containing material properties, sources, and boundary conditions.

It is included in Problem Builder but may also be used separately when only data generation is required.
