Computational mechanics is a vast area of knowledge, which has suffered huge developments in the last decades. A significant number of novel numerical models have been proposed to model either solid or fluid mechanics problems, as well as to deal with solid-fluid coupling problems. Many of these methods are based on a spatial description of the model by points (such as in meshless methods) or on enrichment strategies of elements or nodes of the classic finite element method (such as in the GFEM, XFEM, or EFEM). Many of those methods have proved to be much more efficient than classical formulations and can thus be very interesting to treat applied problems.

We invite authors to contribute original research articles as well as review articles related to all aspects of the application of these novel numerical tools to nontrivial solid and fluid mechanics problems. Potential topics include, but are not limited to:

• Vibrations and elastodynamics
• Fluid-structure interaction
• Fracture and crack propagation
• Material interfaces
• Transient problems
• Linear and nonlinear analysis of complex media
• 3D and large-scale problems
