Guidelines for Choosing the Mesh Mapper

When importing data from different meshes, refer to these guidelines and the following table to choose the mesh mapper:

  • If the meshes are compatible, use the compatible mesh mapper. Compatible meshes have the same node/element numbering.

  • If the meshes are incompatible, use the incompatible mesh mapper. Incompatible meshes have independently meshed geometry.

Can map data based on point coordinates or by scaling both meshes to the same dimension


Note:  Elements are only used for visualization. They do not exist in the database. Only node data is stored.


Nodes Arbitrarily Distributed in Space
  • Incompatible (explicit closest point projection)

  • User-specified direction

  • Incompatible (explicit closest point projection); only if reference mesh is a boundary

  • User-specified direction

Shell Elements
  • Incompatible (explicit closest point projection); Settings: double-sided projection is turned on

  • User-specified direction

  • Incompatible (assuming a smooth boundary)

  • Incompatible (explicit closest point projection)

  • User-specified direction

  • Incompatible (assuming a smooth boundary)

  • Incompatible (explicit closest point projection)

  • User-specified direction

Note:  Works only for the boundaries.

Volume Elements
  • Incompatible (point clouds against volume FEM reference)

  • User-specified direction

  • Incompatible (assuming a smooth boundary)

  • Incompatible (explicit closest point projection)

  • User-specified direction

Note:  Works only for the boundaries.
