Computational fluid mechanics and fluid–structure interaction

Abstract

A number of special issues of this journal on computational fluid mechanics and fluid–structure interaction (FSI) were published in the past fiveyears. These special issues were very successful in terms of the kind of articles included and the attention those articles received following their publication. These research areas of computational mechanics, especially computational FSI, have seen major advances in method power and much expansion in computational challenges addressed. Advances in core computational technologies, including variational multiscale (VMS) methods, space–time (ST) techniques, and isogeometric analysis, and in special techniques targeting specific classes of problems, including biomechanics, parachute FSI, and wind-turbine modeling, played a key role in making that happen. All these motivated the dedication of one of the 25th anniversary special issues of the journal to computational fluid mechanics and FSI. The special issue includes papers focusing on different aspects of this class of problems, including method development, method analysis, meshing and remeshing, mesh refinement studies, computational efficiency, simulation-based analysis and design, verification and blending with experimental data, and industrial applications. The core and special methods presented include arbitrary Lagrangian–Eulerian (ALE) formulations, ST techniques,
