Swept
The Swept node () creates a swept mesh on a domain in 3D by sweeping the mesh from the source face along the domain to an opposite destination face. The source and destination can consist of several connected faces.
You can control the number, size, and distribution of elements using the Size and Distribution subnodes. The Swept node only reads properties from Size nodes defined on the entire geometry or on the domain level and Distribution nodes defined on the domain level.
In domain selection mode, this button works in the same way as the Free Tetrahedral button. In boundary selection mode, the software creates a swept mesh on the remaining domains using the selected boundaries as source faces.
To create a swept mesh:
In the Mesh ribbon toolbar (Windows) or from the Mesh contextual toolbar (macOS and Linux), click the Swept () button.
Right-click a 3D Mesh node and select Swept.
Domain Selection
Specify the domains where you want a swept mesh. Choose the level of the geometry from the Geometric entity level list:
Choose Remaining to specify swept mesh for remaining, unmeshed domains.
Choose Entire geometry to specify swept mesh for the entire geometry.
Choose Domain to specify the domains for which you want a swept mesh. Choose Manual in the Selection list to select the domains in the Graphics window or choose All domains to select all domains.
Source Faces
Click the Active button to toggle between turning ON and OFF selections.
To specify the source faces directly, activate the Source Faces list and select the faces defining the source of the sweep operation in the Graphics window.
Click the Swap Source and Destination button () to swap the faces in the source list above and the faces in the destination list in the Destination Faces section below.
Destination Faces
To specify the destination faces directly, activate the Destination Faces list and select the faces defining the destination of the sweep operation in the Graphics window.
Sweep Method
Face Meshing Method
In the Face meshing method list, you can specify how the unmeshed source faces, which are meshed automatically by the Swept node, are meshed:
Select Quadrilateral (generate hexahedra) to generate a surface mesh with quadrilateral elements. This is the default meshing method.
Select Triangular (generate prisms) to generate a surface mesh with triangular elements.
Select Quadrilateral (legacy version 5.2) to generate a surface mesh with quadrilateral elements using the algorithm used in version 5.2 and earlier versions of COMSOL Multiphysics.
Select Quadrilateral (legacy version 5.2a) to generate a surface mesh with quadrilateral elements using the algorithm used in version 5.2a of COMSOL Multiphysics.
Select Quadrilateral (legacy version 5.4) to generate a surface mesh with quadrilateral elements using the algorithm used in version 5.4 of COMSOL Multiphysics.
Sweeping Path
Use the Swept path calculation list if you want to specify the shape of the sweep path:
The default, Automatic, means that the sweeping algorithm automatically tries to determine if the sweep path is straight or circular; otherwise, a general approach is used.
Sweep following straight lines means that all interior mesh points are located on straight lines between the corresponding source and destination points.
Sweep following circular arcs means that all interior mesh points are located on circular arcs between the corresponding source and destination points.
Sweep using interpolation means that the positions of the interior mesh points are determined by a general interpolation procedure.
Destination Mesh
Use the Destination mesh generation list if you want to specify the method to be used for transferring the source mesh to the destination:
The default, Determine suitable method, means that the algorithm automatically tries to determine a suitable method for creating the destination mesh.
Use a rigid transformation means that the destination mesh is created by a rigid transformation of the source mesh.
Morph source onto destination means that the destination mesh is created from the source mesh by a morphing technique.
Project source mesh onto destination means that the destination mesh is created from the source mesh by a projection technique.
Control Entities
Select the Smooth across removed control entities check box to smooth the transition in element size across removed control entities. You can specify the number of smoothing iterations in the Number of iterations field. In the Maximum element depth to process field you can specify the maximum element depth, from the boundary layer interface, for the mesh points to be smoothed.
Linking Faces
You can choose between two different interpolation methods for the linking faces in the Interpolation method for linking faces list. This specifies how the mapped mesher, which is used by the swept mesher for the linking faces, determines the positions of the interior mesh points. For more information on the different option see Mapped.
