Constructing submeshes

Submesh is a mesh on a geometrical subobject created with algorithms and/or hypotheses other than the algorithms and hypotheses assigned to the parent mesh on the parent object.

If a geometrical subobject belongs to several geometrical objects having different meshes or submeshes, it will be meshed with the hypotheses of a submesh of a lower dimension.
For example, a face of a box is meshed with a submesh using algorithms and hypotheses other than the parent mesh on the whole box. The face and the box share four edges, which will be meshed with algorithms and hypotheses of the submesh on the face, because the face is a 2D object while the box is a 3D object.
If the dimensions are the same, an arbitrary algorithm/hypothesis will be used. This means that an edge shared by two faces each having its own different submesh, will be meshed using algorithms and hypotheses of any of the two, chosen randomly.


Construction of a submesh consists of:


To construct a submesh:

From the Mesh menu select Create Submesh or click "Create Sum-mesh" button in the toolbar.

"Create Submesh" button
The following dialog box will appear:

It allows to define the Name, the parent Mesh and the Geometry (e.g. a face if the parent mesh has been built on box) of the submesh. You can define algorithms and hypotheses in the same way as in Create mesh menu.
In the Object Browser the structure of the new submesh will be displayed as follows:

It contains:
  • a reference to the geometrical object on the basis of which the submesh has been constructed;
  • Applied hypotheses folder containing the references to the hypotheses applied to the construction of the submesh;
  • Applied algorithms folder containing the references to the algorithms applied to the construction of the submesh.
