This option is used to allow ABAQUS/Standard to calculate appropriate areas of integration for ISL- and IRS-type contact elements used in conjunction with CAXAn or SAXAn elements. The *ASYMMETRIC-AXISYMMETRIC option must be used in conjunction with the *INTERFACE option.
Product: ABAQUS/Standard
Type: Model data
Level: Part Part Instance Assembly
Set this parameter equal to the angular position (measured in degrees) of the circumferential plane in which the contact elements exists. Valid values are 
= 0°, 180° for n = 1; = 0°, 90°, 180° for n = 2; = 0°, 60°, 120°, 180° for n = 3; and = 0°, 45°, 90°, 135°, 180° for n = 4. ABAQUS/Standard does not model contact correctly on other circumferential planes.
Set this parameter equal to the number of Fourier modes used with the CAXAn or SAXAn elements that share nodes with the contact elements.
