There are at least three methods that you can use to complete the mesh for
the part. The simplest method would be to create another swept mesh, using the
bottom of the mesh that you just completed and the two faces extending out from
the fillet on the top of the remaining unmeshed area as the source side, the
three geometric vertical faces and the set of vertical element faces as the
connecting sides, and the unmeshed portion of the bottom face as the target
side. This method would complete the part mesh in a single bottom-up meshing
step, and the elements would be fully associated with the selected faces. You
could also use the bottom-up extrude method with the bottom face of the part as
the extrude distance. However, for demonstration purposes we will use a longer
process that combines use of the bottom-up extrude method, the associativity
tool, and the
Edit Mesh toolset.
Select the Extrude method, and click
Select to the right of Source side.
Select the element faces at the bottom of the previous bottom-up mesh,
as shown in
Figure 1,
as the source side for the second bottom-up mesh.
Figure 1. Selecting element faces as the source side.
Click Done in the prompt area to accept the
selected faces.
The Create Bottom-Up Mesh dialog box reappears.
Click the Select button to choose a vector for
the extruded mesh.
Select the upper endpoint of the partition as the starting point of
the vector, and select the lower endpoint as the end of the vector.
Figure 2
shows the extrusion vector.
Figure 2. Selecting the vector for the bottom-up extruded mesh.
Enter 10 for the Number of
layers.
There are 10 elements on the inner face of the top-down swept mesh.
Using the same number of elements for the extruded mesh will provide a better
match when you create the third, and final, bottom-up mesh.
Verify that the extrude depth is set using the default Use
vector length method, and click Mesh in the
Create Bottom-Up Mesh dialog box to create the mesh.

Extend the extruded mesh
Context:
The extruded bottom-up mesh ends near the bottom face of the region, as
dictated by the nonplanar source side and the length of the extrusion vector.
You can edit the nodes in the last extruded element layer so that they end
exactly on the bottom face of the region.
Select the
Edit Mesh toolset
, located at the bottom of the
Mesh module
toolbox.
Select the Node category, and click on
Project in the Edit Mesh dialog box.
Use the
angle
method to select all the nodes on the bottom of the bottom-up extruded
mesh, as shown in
Figure 4,
and then click Done in the prompt area.

Select the bottom face of the bottom-up region, and click
Yes in the prompt area to project the nodes onto the
face.
