Therefore, the low electron density areas inside the solute will be identified by the algorithm as regions where implicit solvent exists, resulting in the emergence of non-physical implicit solvent regions within the solute and even potentially leading to the divergence catastrophe of Kohn-Sham SCF calculations. We present a new and efficient SCCS implementation based on the solvent-aware interface (<em>J. Chem.

Starting with the foundational formulas of SCCS, we have rigorously derived the contributions of the newly defined electrostatic energy to the Kohn-Sham potential and the analytical forces. This comprehensive derivation, which to the best of our knowledge is not available in the current literature, utilizes the updated versions of the solute-solvent interface function and the dielectric function, tailored to align with the specifics of the GPW implementation.

However, the inherent characteristics of ceramic fuels impose limitations on the power density improvement of the heat pipe reactor core. In response to this challenge, an innovative conceptual design of a heat pipe reactor core with U-50Zr metallic fuel is proposed in this study. When addressing the multi-objective, multi-parameter and multi-physics coupling design challenges of heat pipe reactor cores, it is essential to introduce an efficient design and optimization method based on data-driven multi-physics coupling and multi-objective optimization analysis. Therefore, a three-dimensional multi-physics coupling analysis code is developed employing Matlab, OpenMC, and COMSOL. To enhance computational efficiency, the neural network surrogate models are established to replace the original code. Additionally, NSGA-II is utilized to obtain the optimal core design schemes, focusing on the objectives of higher power density of the core and lower fuel enrichment. Finally, in the results of the Pareto front, the detailed multi-physics coupling analyses are studied on two different core design schemes characterized by lower fuel enrichment and higher power density of the core, respectively. The design scheme with high power density features lower peak temperatures and lower peak stresses. In contrast, the design scheme with low enrichment provides a more uniform power distribution and greater backup reactivity. Both design schemes satisfy the operational requirements for a ten-year lifecycle, with temperatures and stresses remaining within the safety limits. This demonstrates the effectiveness of the proposed design approach and the analytical code. This study provides a reference for the design and multi-objective optimization of the heat pipe reactor core with U-50Zr metallic fuel and establishes a foundation for future transient optimization efforts.</div></div>","PeriodicalId":285,"journal":{"name":"Computer Physics Communications","volume":"311 ","pages":"Article 109551"},"PeriodicalIF":7.2,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The program operates within a unified theoretical framework that separates the trajectory-based computation into two stages: initial-condition preparation and trajectory evolution. For initial-condition preparation, we provide several methods, including the Strong-Field Approximation with Saddle-Point Approximation (SFA-SPA), SFA-SPA with Non-adiabatic Expansion (SFA-SPANE), and the Ammosov-Delone-Krainov theory (ADK), with atomic and molecular variants, as well as the Weak-Field Asymptotic Theory (WFAT) for molecules. For trajectory evolution, available options are Classical Trajectory Monte-Carlo (CTMC), which employs purely classical electron trajectories, and the Quantum Trajectory Monte-Carlo (QTMC) and Semi-Classical Two-Step model (SCTS), which include the quantum phase during trajectory evolution. The program is a versatile, efficient, flexible, and out-of-the-box solution for trajectory-based simulations for strong-field ionization.

However, existing computational packages usually require transforming crystal structures adapted to specific conventions, thus hindering extensive application, especially to materials whose symmetries are yet to be identified. To address this issue, we developed a Mathematica package, &lt;span&gt;ToMSGKpoint&lt;/span&gt;, capable of determining the little groups and irreducible (co-)representations of little groups of HSPs, high-symmetry lines (HSLs), and high-symmetry planes (HSPLs) for any nonmagnetic and magnetic crystalline materials in two and three dimensions, with or without considering spin-orbit coupling. To the best of our knowledge, this is the first package to achieve such functionality. The package also provides magnetic space group operations, supports the analysis of irreducible (co-)representations of energy bands at HSPs, HSLs, and HSPLs using electronic wavefunctions obtained from &lt;em&gt;ab initio&lt;/em&gt; calculations interfaced with VASP. Designed for user convenience, the package generates results in a few simple steps and presents all relevant information in a clear tabular format.
