Structural Analysis Workflow for Pump Components

This skill provides a systematic approach to performing Finite Element Analysis (FEA) on pump components, specifically casings and impellers under fluid loads.

FEA Workflow

1. Geometry and Material Definition

Geometry Preparation:

• Import or create CAD geometry of pump casing or impeller
• Simplify geometry by removing non-structural features (small fillets, bolt holes, cosmetic features)
• Identify critical regions: high-stress areas, pressure boundaries, mounting interfaces
• Define coordinate system aligned with pump axis (Z-axis typically along shaft)

Material Definition:

• Assign material properties to all components
• Define isotropic or anisotropic properties as needed
• Input temperature-dependent properties if thermal effects exist
• Consider material orientation for cast or forged components
