Complex engineering analyses usually require the use of numerical methods to provide accurate data. Although nowadays there are several powerful numerical techniques available, such as the Finite Element Method, the Finite Volume Method, the Boundary Element Method, and Meshless Methods, none of them can be considered most appropriate for all kinds of analysis, and usually the coupling of different numerical methodologies is necessary to analyze complex problems more effectively. In this context, several coupling procedures have been proposed over the last decades considering different numerical methods, in order to profit from their respective advantages.

We invite investigators to contribute original research articles as well as review articles that will stimulate the continuing efforts to provide more effective numerical tools by the coupling of different numerical methodologies. We are interested in articles that explore aspects of the coupling techniques themselves or that analyze complex engineering problems by innovative coupling procedures. Potential topics include, but are not limited to:

• Improvement of numerical methods by combined techniques
• Development and testing of novel coupling procedures and hybrid formulations
• Advances in complex analyses by coupled numerical techniques
• Modeling of multiphysics behavior
