Intelligent CFD Assistant Examples

Socratic Learning: Pipe Flow Analysis

๐Ÿง‘โ€๐Ÿ’ป User: "Analyze water flow in a 0.1m diameter pipe at 2 m/s"

๐Ÿค– Claude: Before I run the analysis, let me understand your background better.

๐Ÿ” CLARIFY: "What specifically interests you about this pipe flow - are you designing a hydraulic system, learning about pressure losses, or optimizing an existing installation?"

๐Ÿง‘โ€๐Ÿ’ป User: "I'm learning about pressure losses for my fluid mechanics course"

๐Ÿค– Claude: Perfect! I'll guide you through the analysis step by step.

*Uses run_pipe_flow tool with educational context*

๐Ÿ“Š Results with Learning:
โ€ข Reynolds Number: 200,000 
  ๐Ÿ’ก This indicates turbulent flow (Re > 4,000). What do you think this means for mixing?
โ€ข Friction Factor: 0.0184 (Blasius correlation)
  ๐ŸŒŠ EXPLORE: How would this change if we doubled the velocity?
โ€ข Pressure Drop: 2.4 kPa per meter
  โœ… CONFIRM: So you're seeing that pressure drop increases significantly with velocity - can you explain why?

๐ŸŽฏ APPLY: "Now that you understand the relationship, how would you redesign this pipe to reduce pumping costs by 50%?"

Context-Aware Error Resolution

๐Ÿง‘โ€๐Ÿ’ป User: "My heat transfer simulation isn't converging. The residuals keep oscillating."

๐Ÿค– Claude: I'll help you resolve this using systematic analysis.

*Applies 5 Whys methodology*

๐Ÿ” Why #1: "Why are the residuals oscillating?"
Analysis: Likely numerical instability or inappropriate relaxation factors.

๐Ÿ” Why #2: "Why might the relaxation factors be inappropriate?"
Your setup shows high temperature gradients that require more conservative factors.

๐Ÿ” Why #3: "Why are the temperature gradients so high?"
The boundary conditions show a 500K temperature difference across a thin wall.

๐Ÿ“š Research-Backed Solution:
โ€ข Reduce temperature relaxation from 0.7 to 0.3 (Versteeg & Malalasekera, 2007)
โ€ข Implement under-relaxation for energy equation (Patankar, 1980)
โ€ข Consider CFL number for transient effects

๐ŸŽฏ Prevention Strategy:
โ€ข Always validate physical temperature ranges before simulation
โ€ข Use dimensionless temperature analysis for better conditioning
โ€ข Implement gradual temperature ramping for extreme conditions

Parameter Extraction from Natural Language

๐Ÿง‘โ€๐Ÿ’ป 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."

๐Ÿค– Claude: I can help with this dam break/draining analysis! Let me extract the CFD parameters from your description.

*Uses intelligent parameter extraction*

๐Ÿ“‹ Extracted Parameters (Confidence: 85%):
โ€ข Physics Domain: Multiphase flow (free surface)
โ€ข Initial water height: 2.0 m โœ“
โ€ข Geometry: Tank with bottom orifice โœ“
โ€ข Fluid: Water (ฯ=1000 kg/mยณ, ฮผ=1e-3 Paยทs) โœ“

โ“ Clarification Needed:
โ€ข Tank dimensions (length, width)? 
โ€ข Orifice diameter?
โ€ข Are we modeling turbulence effects?

๐Ÿ” 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*

๐Ÿ“Š Results with Physics Insight:
โ€ข Analytical (Torricelli): ~89 seconds for complete drainage
โ€ข CFD Simulation: ~94 seconds (includes viscous effects)
โ€ข Flow regime: Initially turbulent (Re~50,000), transitions to laminar
โ€ข Vortex formation near orifice affects drainage rate by ~5%
