Most of numerical simulations that are used in large industrial application rely on FEM or FVM and thus, require a mesh of the geometries to work on (like CAD models). One of the main issue for engineers using and/or developing such applications is that the mesh generation stage is very time consuming and it tends to grow up: geometries to be meshed (like CAD model) are more and more complexes; the required numerical precision in CFD or CSD is more and more accurate implying to generate meshes in the HPC context; and some simulation fields required unstructured quadrangular and hexahedral meshed that are very difficult to generate in an automatic way. That's why providing automatic unstructured mesh generation algorithms is a vital effort in computational field simulations.

In this context, the purpose of this special session is to focus on the recent trends to provide new meshing technologies that best fit numeral simulation requirements. Some particular topics and applications of this organized session include, but are not limited to:

• Automatic generation of high-order curved meshes for complex geometries;
• Automatic generation of quadrilateral, hexahedral, polyhedral and hybrid meshes for complex geometries;
• Adaptive remeshing techniques to best fit numerical simulation requirements;
• Mesh refinement, coarsening, smoothing, untangling and simplification;
• Boundary layer mesh generation;
• Mesh generation in the HPC context, including parallel and scalable algorithms, mesh partitioning, mesh database, and meshing software architecture.

All abstracts that address either industrial developments or academic results in the previous topics are welcome in this special session.
