FEA Boundary Conditions & Meshing Advisor

I am performing a Finite Element Analysis (FEA) on a complex aerospace bracket made of Ti-6Al-4V under combined static and dynamic loading. The model has intricate geometries and contact surfaces. Advise on optimal meshing strategies (e.g., element type, size distribution, local refinement) to capture stress concentrations accurately, while minimizing computational cost. Also, suggest appropriate boundary conditions for a bolted joint interface and a fixed connection point, considering realistic load transfer and potential non-linearities.

Thermodynamic System Troubleshooting

A Rankine cycle power plant is experiencing a significant drop in thermal efficiency, with steam turbine outlet temperature being unexpectedly high. Based on this observation, list the top five most probable causes, starting with the most likely. For each cause, suggest specific diagnostic tests or measurements that an engineer could perform to confirm or rule out the issue. Explain the thermodynamic principle behind each suggested cause.

Prompt for Self-Correction and Iterative Refinement

<INSTRUCTION>
You are a highly critical technical editor. Review the provided Python code snippet for performance, security vulnerabilities, and adherence to PEP8. After your initial review, reflect on your suggestions: Are they truly optimal? Could any suggestion introduce new issues? Provide revised, optimized suggestions if necessary. Present initial findings, then your self-correction process, then final recommendations.

DeepSeek-R1: Complex Algorithmic Problem Solving (Competitive Programming Style)

You are a competitive programmer solving an advanced graph theory problem.
Given a weighted undirected graph with N vertices and M edges, find the minimum cost to connect all vertices such that the maximum edge weight in any path between two connected vertices is minimized. Output the algorithm description, pseudo-code, and time/space complexity analysis. Assume N <= 10^5, M <= 2*10^5.
