Without modeling all region, a model can be reduced considering the area of interests by assigning infinite element on the boundary which does not have significant effects on the result. All analysis types are applicable except dynamic analysis. (Free field element is used in dynamic analysis.)

It isn't possible to use all kind of load & boundary condition (Self Weight, Constraint, Nodal Head, Review, etc.) in the node or element of infinite element.

It is divided into ‘Line, and ‘Plane’ tab according to the type. For the adjacent element with infinite element, analysis is only for Quad / Wedge / Hexa typed Low/High order element with 'Plane Strain / Axisymmetric / Solid' property.

Target Object Type : Infinite element can be created by selecting 2D element, ‘Free Edge’ in the case of 'Line' type. Infinite element can be created by selecting 3D element, ‘Free Face’ in the case of 'Plane' type.

Property : Select Line/Plane type infinite element

Infinite Type : Select infinite element type. It is divided into ‘Line’ type and ‘Plane’ type for 2D model and 3D model respectively.

Constitutive Behavior : Select Constitutive Behavior of infinite element. It is divided into ‘From Adjacent Element’ type which adopt material property of adjacent element and ‘User Defined’ type which can assign other material property for only infinite element. ‘Material’ is directly inputted for only 'User Defined' type.
