With the release of Bentley's PLAXIS 3D CONNECT Edition V20 Update 2, the meshing procedure is enhanced with the new Swept Meshing Feature.
Swept meshing refers to the method in which a face of a volume (termed as source face) is meshed and then “swept” along the main volume following its trajectory (termed as sweeping direction), thus creating a volume mesh.
The cross-section of the volume considered should remain constant along the trajectory of the volume, which will allow for the source face to be swept along the sweeping direction.
The benefits of using this mesh method include:
PLAXIS 3D performs an automatic swept mesh detection that consists of two steps: 1. Determining which volumes are suitable for sweeping; and 2. Selecting the compatible set of volumes, considering the possible sweep directions, which will actually be meshed with a structured swept mesh.
The generated mesh in PLAXIS Output program should be always inspected to ensure that it fits the requirements of the calculation.
Swept meshing can be utilized in certain volumes that satisfy the following criteria:
Examples comparing the generated mesh with and without activating the Swept meshing feature can be found in the Image Gallery below.
