Intelligent CFD Assistant Examples

Socratic Learning: Pipe Flow Analysis

🧑‍💻 User: "Analyze water flow in a 0.1m diameter pipe at 2 m/s"

🤖 Claude: Before I run the analysis, let me understand your background better.

🔍 CLARIFY: "What specifically interests you about this pipe flow - are you designing a hydraulic system, learning about pressure losses, or optimizing an existing installation?"

🧑‍💻 User: "I'm learning about pressure losses for my fluid mechanics course"

🤖 Claude: Perfect! I'll guide you through the analysis step by step.

*Uses run_pipe_flow tool with educational context*

📊 Results with Learning:
• Reynolds Number: 200,000 
  💡 This indicates turbulent flow (Re > 4,000). What do you think this means for mixing?
• Friction Factor: 0.0184 (Blasius correlation)
  🌊 EXPLORE: How would this change if we doubled the velocity?
• Pressure Drop: 2.4 kPa per meter
  ✅ CONFIRM: So you're seeing that pressure drop increases significantly with velocity - can you explain why?

🎯 APPLY: "Now that you understand the relationship, how would you redesign this pipe to reduce pumping costs by 50%?"

Context-Aware Error Resolution

🧑‍💻 User: "My heat transfer simulation isn't converging. The residuals keep oscillating."

🤖 Claude: I'll help you resolve this using systematic analysis.

*Applies 5 Whys methodology*

🔍 Why #1: "Why are the residuals oscillating?"
Analysis: Likely numerical instability or inappropriate relaxation factors.

🔍 Why #2: "Why might the relaxation factors be inappropriate?"
Your setup shows high temperature gradients that require more conservative factors.

🔍 Why #3: "Why are the temperature gradients so high?"
The boundary conditions show a 500K temperature difference across a thin wall.

📚 Research-Backed Solution:
• Reduce temperature relaxation from 0.7 to 0.3 (Versteeg & Malalasekera, 2007)
• Implement under-relaxation for energy equation (Patankar, 1980)
• Consider CFL number for transient effects

🎯 Prevention Strategy:
• Always validate physical temperature ranges before simulation
• Use dimensionless temperature analysis for better conditioning
• Implement gradual temperature ramping for extreme conditions

Parameter Extraction from Natural Language

🧑‍💻 User: "I have a large tank with water draining through a small hole at the bottom. The water level starts at about 2 meters and I want to know how long it takes to empty."

🤖 Claude: I can help with this dam break/draining analysis! Let me extract the CFD parameters from your description.

*Uses intelligent parameter extraction*

📋 Extracted Parameters (Confidence: 85%):
• Physics Domain: Multiphase flow (free surface)
• Initial water height: 2.0 m ✓
• Geometry: Tank with bottom orifice ✓
• Fluid: Water (ρ=1000 kg/m³, μ=1e-3 Pa·s) ✓

❓ Clarification Needed:
• Tank dimensions (length, width)? 
• Orifice diameter?
• Are we modeling turbulence effects?

🔍 EXPLORE: "Based on Torricelli's law, what do you expect happens to the flow rate as the tank empties?"

*After clarification, runs multiphase flow analysis*

📊 Results with Physics Insight:
• Analytical (Torricelli): ~89 seconds for complete drainage
• CFD Simulation: ~94 seconds (includes viscous effects)
• Flow regime: Initially turbulent (Re~50,000), transitions to laminar
• Vortex formation near orifice affects drainage rate by ~5%
