Mapped Meshing

Mapped meshing can be used for an entire model or for certain parts of a model, in which case free (unstructured) meshing is used for the remaining parts of the model.

Element Types

  • Brick or tetrahedral elements can be generated using mapped meshing
  • Only tetrahedral elements can be generated using free meshing

Geometry Topology

Mapped meshing can be used on geometry with the following shapes:
  • Hexahedron
  • Prism
  • Pyramid
  • Tetrahedron

The four types of shapes suitable for mapped meshing are illustrated below. The geometry is created using ADINA-M or SolidWorks. Please, click on thumbnails for larger images.

Hexahedral. Prismatic.
Pyramidal. Tetrahedral.

Non-regular Mapped Meshing

Traditionally, mapped meshing requires opposite sides on a face to have matching subdivisions. ADINA also allows non-matching subdivisions on opposite sides of a given face by integrating the use of prismatic elements (wedges) in the mapped meshing scheme. The picture below gives an example of ADINA's "non-regular" mapped meshing. Please, click on thumbnail for larger picture.

Combined Mapped and Free Meshing

In general, an original solid part will not have the simple shape required for mapped meshing. However, it may be necessary or desirable to use mapped meshing on a certain area of the part. The ability to combine mapped mesh with free mesh on a part makes this possible. A certain portion can be "carved" out of the original part for mapped meshing. Free meshing is then used on the rest of the part with compatibility at the interface to the mapped mesh.
