1) Given the same mesh size controls (e.g., the length of mesh edges), the mesh on the initial geometry will: *

1 point

... have *more* elements than the mesh of the defeatured geometric model.

... have *less* elements than the mesh of the defeatured geometric model.

... have the same number of elements as the mesh of the defeatured geometric model.

2) Which partition has the highest vertex imbalance? (grep 'afterSplit entity imbalance' *.out) *

1 point

RCB

RIB

multi-level graph

3) Which partition has the most mesh vertices? (grep 'afterSplit weighted vtx' *.out) *

1 point

RCB

RIB

multi-level graph

4) Which partition has the highest element imbalance? (grep 'afterSplit entity imbalance' *.out) *

1 point

RCB

RIB

multi-level graph

5) What causes the boundaries of the RIB and RCB partitions to look jagged relative to the multi-level graph partition boundaries? (select all that are correct) *

1 point

the placement of the cutting plane versus the coordinates of the mesh elements

the intersection of the cutting planes used by the recursive sectioning procedures form angular multi-part junctions whereas the multi-level graph procedures produce more rounded parts and thus smoother junctions

the multi-level graph procedure uses mesh adjacency information to reduce the number of mesh faces on the partition boundaries

6) Which of the following statements are true? Specifying boundary conditions on the geometric allows users to *

1 point

... change the mesh without having to modify the boundary condition definition

... specify boundary conditions that vary over the geometric model entity

... automate mesh creation and analysis execution

Required

7) How do applications request anisotropic edge lengths from mesh adaptation procedures? *
