Infinite elements

Infinite elements:

  • are used in boundary value problems defined in unbounded domains or problems in which the region of interest is small in size compared to the surrounding medium;

  • are usually used in conjunction with finite elements;

  • can have linear behavior only;

  • provide stiffness in static solid continuum analyses; and

  • provide “quiet” boundaries to the finite element model in dynamic analyses.

A solid section definition is used to define the section properties of infinite elements.
