Aims

Journal of Complex and Multiphysics Engineering Systems (JCMES) is an international, peer-reviewed, open-access journal devoted to the study of engineering systems in which multiple physical processes interact and jointly influence system behaviour. The journal publishes research on the modelling, analysis, and design of systems governed by thermal, mechanical, fluid, electromagnetic, chemical, and micro-scale phenomena, particularly where their interaction plays a material role in system performance.

Engineering systems in contemporary practice frequently operate under conditions where more than one physical mechanism is active. Interactions among these mechanisms may affect stability, transport processes, structural response, durability, and overall operational characteristics. JCMES provides a forum for research that examines such interactions in a systematic and technically rigorous manner, with attention to their implications for engineering analysis and design.

The journal is concerned with how interacting physical processes influence system behaviour at the component and system levels. Emphasis is placed on clear physical interpretation, well-defined modelling assumptions, and demonstrable technical contribution. Submissions should extend beyond routine computation or incremental parametric variation and should offer substantive insight into engineering mechanisms, modelling approaches, or system-level understanding.

While particular attention is given to systems involving interacting fields, the journal also considers high-quality studies of engineering field behaviour more generally, including single-field investigations, where the work presents methodological development, improved modelling frameworks, or findings with clear relevance to system performance or design considerations.

Contributions may be theoretical, computational, experimental, or integrative. Regardless of approach, manuscripts are expected to demonstrate analytical consistency, technical depth, and reproducibility of results.

JCMES is published quarterly by Acadlore. All submissions undergo structured peer review to ensure technical soundness and clarity of presentation.

Key features of JCMES include:

• The journal focuses on engineering systems influenced by interacting physical processes, rather than on isolated disciplinary classifications.

• It addresses system behaviour arising from coupled mechanisms, multi-scale effects, and interface-driven phenomena across a range of engineering domains.

• Contributions are expected to integrate sound physical reasoning with appropriate analytical, numerical, or experimental support.

• Both foundational modelling work and application-oriented studies are considered, provided they demonstrate clear technical substance and clear relevance to engineering system behaviour or design.

• Particular attention is given to methodological transparency and consistency of analysis.

Scope
