SFSF

Model ElementDefines a surface-to-surface higher pair constraint element.

Example

SFSF/1, IRM=30103020, JRM=30102010, IFLOAT=30104032
, JFLOAT=30103032, ISURFACE = 111, JSURFACE = 555

SFSF/id, IFLOAT = id, ISURFACE = id, IRM = id
 , JFLOAT = id, JSURFACE = id, JRM = id
[, IDISP = x, y, z [,IICM=id] ]
[, JDISP = x, y, z [,JICM=id] ]

id: Element identification number (integer>0).
IDISP: Specifies the x, y, and z coordinates of the initial point of contact on the I surface in the IICM marker reference. If IICM is not specified, then IRM marker is used as reference. If the point specified is not exactly on the I surface, then the nearest point on the I surface is computed by the solver and used instead.
IFLOAT: ID of the I floating marker which belongs to the body containing the I surface.
IICM: ID of the marker used as reference for defining IDISP.
IRM: ID of the marker used to define the I surface.
JDISP: Specifies the x, y, and z coordinates of the initial point of contact on the J surface in the JICM marker reference. If JICM is not specified, then the JRM marker is used as reference. If the point specified is not exactly on the J surface, then the nearest point on the J surface is computed by the solver and used instead.
JFLOAT: ID of the floating marker that is always positioned at point of contact. This marker is oriented such that the z-axis is normal to the surface.
JICM: ID of the marker used as reference for defining JDISP.
JRM: ID of the marker used for defining the J surface.
ISURFACE: ID of the I surface.
JSURFACE: ID of the J surface.
