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.
Tips:
  • 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.

Inputs

NameTypeDescription
MeshFE MeshThe finite element mesh.
EntityFE Interior Region EnumThe type of mesh entity to select.
BodyImplicit BodyThe implicit body to select with.
ReverseBoolOption to select entities outside the implicit body instead of inside.
ToleranceScalarThe tolerance for checking at the implicit body’s region. a positive value will effectively extend the region while a negative value will shrink it.
