About this Block
What it does: Selects the FE Mesh elements whose center of mass lies within the tolerance value of the implicit body. Commons uses:- Choosing areas for defining material and elemental properties.
- Choosing elements for Boundary Conditions.
- This block selects elements that are present within the FE Mesh. These elements include beams, shells, or cells (including interior cells).
-
How to decide which Entity type to choose:
- Choosing your entity depends on the type of elements available in the mesh.
- Cells can only be selected on an FE Volume Mesh.
- Shells can only be selected on FE Surface Mesh and FE Lattice Mesh (only if the lattice contains faces).
- Beams can only be selected on beam-based FE Lattice Meshes.
- Choosing your entity depends on the type of elements available in the mesh.

Select elements in an FE Mesh using an Implicit Body. Elements with their center of mass lying within a defined tolerance of the Implicit Body will be selected.
Inputs
| Name | Type | Description |
|---|---|---|
| Mesh | FE Mesh | The finite element mesh. |
| Entity | FE Interior Region Enum | The type of mesh entity to select. |
| Body | Implicit Body | The implicit body to select with. |
| Reverse | Bool | Option to select entities outside the implicit body instead of inside. |
| Tolerance | Scalar | The tolerance for checking at the implicit body’s Region. A positive value will effectively extend the region while a negative value will shrink it. |
