Comparing the Sweep and MultiZone Methods

Sweep or MultiZone?

Use Sweep Method when:

-You have a multibody part where some bodies should be meshed with Sweep, and some with Patch Conforming Tet

If you want to use advanced size function

-Preview Sweepable bodies shows that all bodies are sweepable

Use MultiZone when:

-You are meshing single body parts that are too complicated for traditional sweep approach.

-You have multiple sources and targets you need to respect (can’t use VTs to group into a single source/target)

-You need to inflate off source and side faces

Comparing Thin Sweep and MultiZone

Thin Sweep or MultiZone?

Use Thin Sweep Method when:

-You have a “thin” solid part where the source and target faces don’t exactly match, and you don’t care about the features on the target side.

Use MultiZone When:

-You have a “thin” solid part where the source and target faces don’t exactly match, and you care about the features on both sides.

Note, MultiZone will ignore the internal cutouts unless they are in a Named Selection
