Assembly Meshing Wizard
Design goals
One comprehensive user interface
Intuitive approach for solid pairs

specification
Mesh seed and Mesh control
Surface tri elements
Automatic global edge length calculation

Additional requirements
Check imprint boundaries before meshing
Create solid tet mesh individually
Check the boundary between meshed solids




Слайд 309/08/2018
Imprint
Select All solids to be assembled
All solids which should be connected

are required to be selected as the first step

Select solids to be removed from assemblies
Define solid pairs which are not required to be connected

Check the imprint boundary
If check is ON, boundaries appears after imprint execution



Слайд 409/08/2018
Boundary Check
Imprinted boundaries can be seen within transparency solids


Слайд 509/08/2018
Mesh Seed and Mesh Control
Mesh seed and Control surface tri-elements can

be applied after Imprint

Слайд 609/08/2018
Meshing
Select solids to be meshed
The target solids should have already been

imprinted

Select mesh size and priority to solid
Mesh size can be defined to each solid
Meshing priority can be also defined

Define the global edge length
This value is applied to the solids with no previously defined mesh size and priority

Mesh Results
Congruent meshes are created except the boundary removed from assemblies
