Configuring the Global Mesh

 

The global mesh is defined and configured using the Mesh options dialog box in Advance Design. In addition, for each linear and planar element, the mesh details are configured locally in their properties list.

How to configure the global mesh

Follow these simple steps to configure the global mesh:

 

  1. Open the Mesh options dialog box.

  2. Select the mesh type (Grid or Delaunay).

  3. In the Element type area, select the shape of the mesh elements (for planar elements): Triangles and Quadrangles, Only quadrangles or Only triangles.

  4. You can select if you want to include loads in the mesh (linear/planar elements).

  5. In the Element size by default field, define the mesh unit size by entering a value (in meters).

  6. In the Mesh tolerance field, define the minimal distance required for two nodes to be distinct by entering a value (in meters).

  7. Click OK to apply the settings and close the dialog box.

 

How to define a default global mesh

If you need to define a default global mesh, use the steps highlighted below:

 

  1. Open the Mesh options dialog box.

  2. Make the desired settings for the mesh configuration.

  3. Click Define by default.

  4. Click OK.

The current settings will be used in all Advance Design projects.

  1. Open the Mesh options dialog box.

  2. Select the mesh type (Grid or Delaunay).

  3. In the Element type area, select the shape of the mesh elements: Triangles and Quadrangles.

  4. In the Element size by default field, define the mesh unit size by entering a value (in meters).

  5. In the Mesh tolerance field, define the minimal distance required for two nodes to be distinct by entering a value (in meters).

  6. Click OK to apply the settings and close the dialog box.

 

 

How to define the shape of the mesh elements

For each mesh type (i.e., Delaunay and Grid) it is possible to define the shape of the mesh elements (for planar elements):

 

  1. Triangles and Quadrangles (T3-Q4)

Splits the planar elements in parallelepiped and triangular meshes with a node on each vertex.

Mesh - Triangles and Quadrangles (T3-Q4)

 

 

  1. Only Quadrangles

Creates a Q4 mesh type, parallelepiped meshes with a node on each vertex (only for Delaunay mesh). To obtain only a quadrangles mesh, the number of mesh units between nodes must be even for each planar element.

Mesh - Only Quadrangles

 

 

  1. Only Triangles

Creates a T3 mesh type, triangular meshes with a node on each vertex.

Mesh - Only Triangles

 

 

  1. Middle node (T6-Q9)

Creates a middle node for each mesh unit. You can combine this option with each mesh type:

 

Creates a Q9 mesh type, parallelepiped meshes with a node on each vertex, a node in the middle of each side and a node in the center.

Mesh - Quadrangles + Middle node

 

 

Creates a T6 mesh type, triangular meshes with a node on each vertex and a node in the middle of each side.

Mesh - Triangles + Middle node

 

 

Include loads in the mesh

When enabled (default), the meshing takes into account the loads applied on the structure elements. When disabled, the loads do not affect the meshing of the elements.
