CalculiX Input Deck Formatter

When to use this CalculiX helper

• Use it while preparing, organizing, formatting, or documenting CalculiX-related input text before human review.
• Use it for learning CalculiX keyword structure, material-card organization, output-request planning, or report documentation.
• Use it before transferring final text into a controlled project folder, version-control workflow, or validated solver setup.

How to use

1. Enter only the small model, material, text, or CSV values needed for the helper.
2. Review the browser-local privacy notice before generating any CalculiX-related text.
3. Click the exact action button; default values, typed edits, URL-prefilled values, and worked examples do not generate final output automatically.
4. Review warnings, generated text, preview visual, assumptions, limitations, and downloads before copying output into a real workflow.

Input guide

Input deck text

Pasted plain-text CalculiX deck excerpt, not uploaded and not executed.

Keyword lines

Lines beginning with `*` are normalized for readability.

Length limit

Long decks are bounded so the browser-local formatter remains responsive.

Notation

Output interpretation

• The output is formatted `.inp` text, keyword count, warnings when no keyword lines are found, preview visual, copy action, and safe download.
• Warnings identify missing data, placeholder values, unit risks, or review needs; they are not solver diagnostics.
• Downloads and copy buttons appear only after successful generation and disappear when the output is stale.

Supported CalculiX helper use cases

• Input deck skeletons, material cards, boundary templates, load-step templates, element-type guidance, result-file review notes, deck formatting, small pasted CSV material tables, and Markdown report templates.
• Plain-text snippets for student, research, and preliminary engineering review workflows.
• Safe local output generation with bounded text length and fixed download filenames.

Unsupported patterns

• CalculiX solver execution, cloud simulation, mesh generation, CAD/mesh parsing, binary .frd parsing, Abaqus conversion, convergence certification, AI APIs, databases, authentication, analytics, tracking, payments, or server uploads.
• Official CalculiX support, model validation, material-database certification, or final engineering approval.
• Automatic transfer of detailed project data through URLs or persistent browser storage.

Output interpretation

• Treat generated snippets as editable starting points and compare them against the official manual for your installed release.
• Confirm every set name, element type, unit convention, material value, boundary condition, load, and output request before solving.
• Use generated report and checklist text to organize review evidence, not as proof that the simulation is valid.

Practical review guidance

• Keep unit conventions visible beside every material, load, and output decision.
• Use small hand checks, reaction balance, mesh sensitivity, and expected trend checks before trusting detailed FEA output.
• Version-control final decks and reports outside the browser so project decisions remain traceable.

Worked examples

Assumptions

• CalculiX syntax and solver behavior can depend on the installed version and the full input deck context.
• User-entered unit conventions are treated as notes; the helper does not infer or enforce a complete unit system.
• Generated snippets are starter text for human review, not solver-validated model files.

Practical guidance

• Replace generated placeholders with verified project data before running any solver outside ScholarTool.
• Keep generated snippets short and reviewable; use project version control for final decks.
• Use the related tools to move from material cards to deck formatting, result review, and report documentation.

Common mistakes

• Copying generated placeholders into a solver deck without replacing node, element, set, load, and material data.
• Mixing SI, millimeter-Newton-second, MPa-mm, or US customary values without a documented unit convention.
• Treating a formatted deck or generated report as evidence that the model has converged or is physically valid.
• Using starter element guidance without mesh sensitivity, reaction checks, and result sanity checks.

Limitations

• The helper does not run CalculiX, execute solver commands, validate convergence, parse binary result files, or inspect local files.
• Mesh quality, contact setup, material certification, boundary-condition correctness, and physical validation remain outside this helper.
• Official documentation, validated solver workflows, standards, and qualified finite element review remain required for critical decisions.
