hpc-calculix

Build, review, debug, and automate CalculiX finite-element workflows. Use when working with CalculiX `.inp` decks, Abaqus-style keywords, materials, steps, contacts, boundary conditions, static or frequency analyses, or CalculiX solve and post-processing issues.

HPC CalculiX

Treat CalculiX as an input-deck-driven FEM workflow centered on .inp keywords.

Start

  1. Read references/input-deck-manual.md before creating or editing a .inp file.
  2. Read references/keyword-and-step-matrix.md when mapping materials, sections, loads, and analysis steps.
  3. Read references/mesh-boundary-and-output.md when working with nodes, elements, sets, boundary conditions, and result output.
  4. Read references/cluster-execution-playbook.md when staging a CalculiX deck for scheduler-backed cluster execution.
  5. Read references/error-recovery.md when parsing, solving, or post-processing fails.

Additional References

Load these on demand:

  • references/time-control-and-amplitudes.md for step time, amplitude logic, and incremental loading behavior
  • references/result-files-and-postprocessing.md for .dat, .frd, and eigenmode artifacts
  • references/thermal-and-coupled-procedures.md for heat transfer and coupled analysis patterns
  • references/step-load-output-matrix.md for procedure-to-load-to-output compatibility tables
  • references/element-section-material-matrix.md for element, section, and material assignment lookup tables
  • references/error-pattern-dictionary.md for structured parse, singularity, and procedure-mismatch failure signatures
  • references/cluster-execution-playbook.md for launch style, result-artifact planning, and cluster-side deck execution

Reusable Templates

Use assets/templates/ when a concrete .inp scaffold is needed, especially:

  • static_minimal.inp
  • frequency_minimal.inp
  • thermal_minimal.inp
  • beam_static.inp
  • calculix-ccx-slurm.sh

Guardrails

  • Do not invent Abaqus-style keywords that CalculiX does not support.
  • Do not mix node or element set names inconsistently across sections and steps.
  • Do not define loads and boundary conditions without checking the active step type.
  • Do not skip material and section coherence when the deck fails later in the solve.

Outputs

Summarize:

  • analysis type
  • materials and sections
  • sets and boundary assumptions
  • step sequence
  • expected result files
