Abstract
Issues related to curvilinear mesh generation starting from a CAD model are addressed. Curvilinear mesh geometry representation in the context of p-version finite elements and its impact on the validity of curvilinear meshes is discussed. A set of meshing tools is described for generation and modification of curved meshes in three-dimensional space. An iterative algorithm for curved meshing of existing straight-edged meshes is described and example curvilinear meshes of complex geometric models are presented
