What is HPC CalculiX?
HPC CalculiX is a specialized integration within the Openclaw Skills ecosystem designed for engineers and researchers working with high-performance computing (HPC) and finite-element method (FEM) simulations. It focuses on the creation and management of .inp decks, adhering strictly to the specific keyword requirements and syntax of CalculiX.
This skill transforms the AI agent into a technical consultant capable of mapping complex materials, sections, and loads into valid simulation steps. By leveraging Openclaw Skills, users can ensure their simulation files are optimized for scheduler-backed cluster execution while avoiding the common pitfalls of unsupported Abaqus-style keywords or inconsistent set naming.
HPC CalculiX Use Cases
- Creating static, frequency, or thermal analysis scaffolds for CalculiX.
- Debugging failed solves by parsing error patterns and singularity signatures.
- Staging FEM decks for execution on HPC clusters using Slurm or other schedulers.
- Validating material and section coherence across complex multi-step simulations.
- Converting physical boundary conditions into valid keyword-driven input decks.
How HPC CalculiX Works
- The agent initializes by referencing the input-deck-manual to establish the syntactic foundation for the .inp file.
- It maps the simulation requirements against the keyword-and-step-matrix to define materials, sections, and loads.
- The skill configures node and element sets while verifying mesh-boundary compatibility.
- If intended for a cluster, it applies the cluster-execution-playbook to generate appropriate job submission scripts like Slurm wrappers.
- Upon completion or failure, it utilizes the error-recovery and post-processing modules to interpret result artifacts or solve issues.
HPC CalculiX Setup
To integrate this capability into your environment, ensure you have the Openclaw Skills framework installed and the reference library available in your local repository.
# Clone the CalculiX skill assets
git clone https://github.com/openclaw/hpc-calculix-skill.git
# Verify the templates directory
ls assets/templates/
# Initialize the skill within your agent config
openclaw install hpc-calculix
HPC CalculiX Data Schema & Taxonomy
The skill manages a structured hierarchy of documentation and templates to ensure simulation integrity:
| Directory | Content Type | Purpose |
|---|---|---|
references/ |
Markdown Docs | Technical specs for keywords, matrices, and error patterns. |
assets/templates/ |
.inp & .sh |
Reusable scaffolds for static, frequency, and thermal runs. |
outputs/ |
Simulation Logs | Summaries of analysis types, step sequences, and result files. |
Data organization emphasizes consistency between node/element sets and their corresponding section assignments.
