Lab Note: High-Fidelity Simulation Benchmarks

Status: Ongoing Date: January 2026

Overview

Testing Hesva simulation engine across various physics scenarios to establish accuracy-performance baselines. Goal is to identify which fidelity tradeoffs are acceptable for research applications.

Test Scenarios

Rigid Body Dynamics

  • Accuracy: 99.7% match with analytical solutions
  • Performance: 10,000 bodies at 60Hz on single GPU

Fluid Dynamics

  • Accuracy: Acceptable for macro-scale phenomena
  • Performance: 1000x faster than real-time for low-Reynolds flows
  • Limitation: Turbulence modeling remains approximate

Multi-Agent Interactions

  • Accuracy: Good agreement with empirical data for up to 1000 agents
  • Performance: Scales linearly to 100,000 agents
  • Limitation: Behavioral complexity limited by computational budget

Key Finding

Sweet spot exists at ~1000x real-time speed with 95% accuracy for most research applications. Higher fidelity available but rarely needed.

Next Steps

Characterize accuracy degradation patterns. Develop adaptive fidelity selection based on research needs.
