Parameters

Name: Type: System String
The name of an existing friction isolator-type link property.

DOF: Type: System Boolean

Fixed

Type:

System Boolean
This is a boolean array, dimensioned to 5, indicating if the specified degree of freedom is fixed (restrained).

Value	Fixity
Fixed(0)	U1 fixity if DOF(0) = True
Fixed(1)	U2 fixity if DOF(1) = True
Fixed(2)	U3 fixity if DOF(2) = True
Fixed(3)	R1 fixity if DOF(3) = True
Fixed(4)	R2 fixity if DOF(4) = True
Fixed(5)	R3 fixity if DOF(5) = True

Nonlinear

Type:

System Boolean
This is a boolean array, dimensioned to 5, indicating if nonlinear properties exist for a specified degree of freedom.

Value	Nonlinear
Nonlinear(0)	U1 has nonlinear properties
Nonlinear(1)	U2 has nonlinear properties
Nonlinear(2)	U3 has nonlinear properties
Nonlinear(3)	R1, not used
Nonlinear(4)	R2, not used
Nonlinear(5)	R3, not used

Note that this item is applicable only for degrees of freedom U1, U2 and U3. For those degrees of freedom, the term Nonlinear(n) applies only when DOF(n) = True and Fixed(n) = False.

Ke: Type: System Double

Ce: Type: System Double

K: Type: System Double

Slow

Type:

System Double
This is an array of the friction coefficient at zero velocity terms for the link property. This coefficient applies for nonlinear analyses.

Value	Slow
Slow(0)	U1, not used
Slow(1)	U2
Slow(2)	U3
Slow(3)	R1, not used
Slow(4)	R2, not used
Slow(5)	R3, not used

Note that this item is applicable only for degrees of freedom U2 and U3. For those degrees of freedom, the term Slow(n) applies only when DOF(n) = True, Fixed(n) = False, and Nonlinear(n) = True.

Fast

Type:

System Double
This is an array of the friction coefficient at fast velocity terms for the link property. This coefficient applies for nonlinear analyses.

Value	Fast
Fast(0)	U1, not used
Fast(1)	U2
Fast(2)	U3
Fast(3)	R1, not used
Fast(4)	R2, not used
Fast(5)	R3, not used

Note that this item is applicable only for degrees of freedom U2 and U3. For those degrees of freedom, the term Fast(n) applies only when DOF(n) = True, Fixed(n) = False, and Nonlinear(n) = True.

Rate

Type:

System Double
This is an array of the inverse of the characteristic sliding velocity terms for the link property. This item applies for nonlinear analyses.

Value	Rate
Rate(0)	U1, not used
Rate(1)	U2 [s/L]
Rate(2)	U3 [s/L]
Rate(3)	R1, not used
Rate(4)	R2, not used
Rate(5)	R3, not used

Note that this item is applicable only for degrees of freedom U2 and U3. For those degrees of freedom, the term Rate(n) applies only when DOF(n) = True, Fixed(n) = False, and Nonlinear(n) = True.

Radius

Type:

System Double
This is an array of the radius of the sliding contact surface terms for the link property. Inputting 0 means there is an infinite radius, that is, the slider is flat. This item applies for nonlinear analyses.

Value	Radius
Radius(0)	U1, not used
Radius(1)	U2 [L]
Radius(2)	U3 [L]
Radius(3)	R1, not used
Radius(4)	R2, not used
Radius(5)	R3, not used

Note that this item is applicable only for degrees of freedom U2 and U3. For those degrees of freedom, the term Radius(n) applies only when DOF(n) = True, Fixed(n) = False, and Nonlinear(n) = True.

Damping: Type: System Double

DJ2: Type: System Double

DJ3: Type: System Double

Notes: Type: System String

GUID: Type: System String
The GUID (global unique identifier), if any, assigned to the property.

Return Value

Returns zero if the property is successfully retrieved; otherwise it returns a nonzero value.
