Embedded Region

The Embedded Region feature allows users to define the interaction between embedded elements and a surrounding host continuum. It is particularly useful for modeling inclusions, reinforcements, or monitoring devices placed within other structural elements.

For more technical background, refer to the Theory Manual or implementation details in the documentation.

The Embedded Region command constrains the motion of embedded elements so that they follow the deformation of the surrounding host elements, without influencing the overall stiffness or stress state (in absorbed mode).

Method Types

Currently, the supported method is:

Absorbed

  • Embedded elements do not contribute to the global stiffness matrix.
  • Embedded nodes are constrained using interpolation of host element shape functions.
  • Nodes outside the host elements are treated normally (active in global system).

How to Configure Embedded Region

Go to the Embedded Region section.
Choose absorbed as the method.
Define the required sets:
- Embedded Element Set – the elements to embed
- Embedded Node Set – the nodes to constrain
- Host Element Set – the surrounding elements acting as the host
Save the region. Nodes within or on the host elements will follow their motion.
