Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If first principles calculations are performed with high accuracy settings, then calculation accuracy is improved, but computing time and resource requirements increase significantly
Solution Approach 1:
The system performs preliminary convergence tests to determine optimal calculation parameters before executing full first principles calculations. This preliminary action identifies the minimum necessary computational settings to achieve adequate accuracy, preventing unnecessary computation time while maintaining result quality.
Solution Approach 2:
The system automatically adjusts calculation parameters such as k-point sampling density, energy cutoff, and convergence criteria based on the specific material system being studied. By dynamically changing these parameters rather than using fixed high-accuracy settings, the system achieves accurate results with reduced computing time.
2Measurement precision
If manual extraction of physical parameters is performed, then extraction accuracy can be controlled, but labor time and operational complexity increase
Solution Approach 1:
The system implements automated scripts that perform parameter extraction from first principles calculation output files. The extraction process is self-service, requiring minimal user intervention while maintaining consistent and reproducible results. The automated scripts parse calculation outputs and extract relevant physical parameters directly.
Solution Approach 2:
The system introduces an intermediary layer of automated processing scripts that bridge the gap between first principles calculation outputs and device-scale simulation inputs. This intermediary automatically transforms raw calculation data into extracted physical parameters, eliminating manual intervention while ensuring accuracy through systematic data processing.
3Measurement precision
If the number of first principles calculations is increased to improve material characterization, then characterization quality is improved, but computing resource requirements increase
Solution Approach 1:
The system performs a limited number of targeted first principles calculations focused on the most critical material properties and defect configurations. Rather than exhaustively calculating all possible parameters, the system identifies and calculates only the essential parameters needed for device-scale modeling, achieving adequate characterization with fewer calculations.
Solution Approach 2:
The system performs preliminary analysis to identify which material properties and defect configurations are most relevant to the device performance being studied. This preliminary action guides the selection of which first principles calculations to perform, ensuring computational resources are focused on the most impactful calculations rather than exhaustive sampling.
