This paper presents the automatic mesh generator Visual DoMesh. This
is a software which is designed to create curved hexahedral and tetrahedral elements
for the discretization of mixed structures. To this end, the recursive domain division
is utilized for the generation of triangular and quadrilateral meshes of freeform
surfaces. Hexahedral elements are formed by a projection approach which extrudes
quadrilateral elements generated on reference surfaces with respect to predefined
mathematical rules. The generation of tetrahedral elements is performed by the
advancing front algorithm as implemented in Netgen. Quasi-regional mapping is
applied to represent curved high order solid elements.
