Description: The volume fraction tool is a subset of the Discrete Field toolset in Abaqus/CAE. The tool compares two intersecting part instances—a meshed Eulerian part and an arbitrary “reference” part—to determine the region of overlap between them. A discrete field is created that assigns each element in the Eulerian part a volume fraction based on the percentage of space within the element also occupied by the reference part instance. You can subsequently use this discrete field to create an Eulerian material assignment that conforms to the geometry of the reference part.

When using the volume fraction tool, you can now create a set of all elements connected to elements with nonzero volume fractions in the discrete field, as shown in Figure 8–1.
