You can use a partition hexahedron mesh to create a highly structured hex-dominant mesh
in a solid part, which is partitioned into multiple volumes. A partition hexahedron
mesh contains a mixture of first-order hex-dominant elements and first-order
(linear) tetrahedron elements. Often, this combination provides the most efficient
way to achieve accurate simulation results.
In this example, the bridge structure has two volumes (a T-shaped print part and its supports)
and requires a smooth mesh between the volumes throughout the structure. Using a
hexahedron mesh for both volumes ensures a smooth mesh.
-
From the Mesh section of the action bar, click Partition Hex
Mesh
.
-
Name the partition hex mesh
Hex_Mesh_Bridge_structure.
-
From the 3D area, select the bridge structure as the
Support.
-
For Non-hex volumes, select Linear
tet.
-
Enter a mesh size of 0.5 mm.
-
Click Mesh, and then click
OK.
-
If the mesh is not visible, right-click FEM_AM in
the tree, and click
Hide/Show.
