Rigid Analytical Surface Contact (Simcenter Samcef)

To define a general contact of a flexible surface to a rigid surface, use the Rigid Analytical Surface Contact simulation object.

Rigid Surface Definition

In the Rigid Surface Definition dialog box, you can define any of the following rigid surface:

• Sphere

• Infinite Cylinder

• Infinite Plane

• Cylinder with Flat Ends

• Cylinder with Spherical Ends

• Parallelepiped with Fillets

You define the surface orientation with a local coordinate system.

You can also enable the display of the analytical surface with dummy elements for post-processing purposes. For more information, see Display of the analytical surface of a Rigid Analytical Simcenter Samcef contact in post-processing.

Master node and target region

In the Master Node dialog box, you can attach the rigid surface to any of the following:

• Mesh point

• Node

• Point

In the Target Region (slave) group, you can define the flexible surface as a Surface Region or Edge Region.

Options

In the Contact Configuration, Topology Search, or Normal behavior groups, you can define the contact options.

When you solve or export your model, the options in the Rigid Analytical Surface Contact dialog box define a Samcef .MDS command. The contact will also generate Samcef SURF elements.

Select the Show Ancillary Display check box to display the ancillary view of the contact constraint in the graphics window. The software launches the Samcef contact conditions quick solver to compute this view.

Supported analysis solutions

The Rigid Analytical Surface Contact simulation object is available for all structural Samcef solutions.
