Specifies the maximum slide line and surface contact element activation distance. The primary purpose of this parameter is to prevent unnecessary generation of contact segments when little or no movement is expected. For general and rough contact penetration types, the default value is AUTO in linear solutions and 1.0E+30 in nonlinear solutions. For all other penetration types, the default is AUTO. For all contact types except welded, the AUTO setting defines an activation distance value for each element of the primary surface equal to the maximum edge length of that element. For welded contact, the AUTO setting defines an activation distance value for each element of the primary surface equal to the maximum edge length of that element multiplied by 30.0*SLINEPOSTOL. The AUTO setting will restrict contact generation to adjacent elements, while the 1.0E+30 setting will generate contact to allow unlimited movement. The AUTO setting is recommended for optimal performance when little or no movement is expected, such as with bolted connections. Note that a zero value should only be used if all primary and secondary nodes are collocated. |
