Abaqus Modal Analysis Skill

Extract natural frequencies and mode shapes from a structure. Use for vibration analysis, resonance avoidance, and dynamic characterization.

When to Use This Skill

Route here when user mentions:

• "Natural frequency", "modal analysis", "vibration"
• "Resonance", "mode shapes", "eigenvalue"
• "How will it vibrate?", "avoid resonance at X Hz"
• "First mode frequency", "natural frequency of beam/plate"

Route elsewhere:

• Forced vibration response → use transient dynamic
• Frequency response function → use steady-state dynamics
• Static stress/deflection → /abaqus-static-analysis
• Impact/crash → /abaqus-dynamic-analysis
