CalculiX Modal Analysis
Free-vibration eigenanalysis on a CalculiX deck: a *FREQUENCY step requests N
eigenpairs; ccx prints the eigenvalue table and per-mode eigenvectors to the
.dat, so both frequencies and mode shapes parse from text (no .frd needed).
When to Use
Use when an agent must extract natural frequencies, check resonance/vibration
margins, or visualize mode shapes on a CalculiX model. Driven by the same MCP
tools as static runs (run_solver → read_results → export_results).
Not for: static stress/deflection (use calculix-fem), transient/dynamic
response (not yet supported), or sizing optimization (calculix-sizing-optimization).
