Описание: I recently came across Gmsh, an open-source 3D finite element mesh generator available at https://gmsh.info/. Beyond its meshing capabilities, this tool features an intuitive graphical user interface for creating fundamental geometric shapes. While it excels in meshing 3D domains with tetrahedral elements, it encounters challenges when meshing with hexahedral elements, which are often preferred in finite element methods due to their enhanced accuracy.

In this context, I present a straightforward illustration involving the creation of a cylindrical domain atop a cuboidal base. The aim is to mesh this structure using hexahedral finite elements through an extrusion process. The version of Gmsh employed for this demonstration is 4.8.4.
