CalculiX Input Deck Generator

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

Job and model title

Readable identifiers for the deck heading and review notes.

Analysis type

Static, frequency, thermal, buckling, or generic guidance for the step placeholder.

Element and set names

Starter element type plus node-set and element-set labels that must exist in the final deck.

Boundary/load type

Controls which placeholder *BOUNDARY, *CLOAD, *DLOAD, or thermal note is emitted.

Comment style

Controls compact, educational, or checklist-friendly comments in the generated text.

Notation

Output interpretation

• The output is editable `.inp` text plus a section breakdown, missing-data checklist, warnings, preview flow, 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.
