3. Minimum time increment allowed. Only used for automatic time incrementation. If

ABAQUS/Standard ﬁnds it needs a smaller time increment tha nth is value, the analysis is

terminated. If this entry is zero, a default value of the smaller of the suggestedinitial time

increment or 10−5 times the total time period is assumed.

4. Maximumtim e increment allowed. Only u sed for automatic time incrementation. Ifthis value

is not speciﬁed, no upper limit is imposed.

Data line for the Riks method:

First (and only) line:

1. Initial increment in arc length along the static equilibrium path in scaled load-displacement

space, . If the DIRECT parameter is used, this value will be used as a constant arc length

increment. If this entry is zero or is not speciﬁed, a default value that is equal to the total arc

length of the step is assumed.

2. Total arc length scale factor associated with this step, . If this entry is zero or is not

speciﬁed, a default value of is assumed.

3. Minimum arc length increment, . If this entry is zero, a default value of the smaller of

the suggested initial arc lengthor 10−5 times the total arc length is assumed.

4. Maximumarc length increm ent, . If this value is not speciﬁed , no upper limit is imposed.

5. Maximum value of the load proportionality factor, . This value is used to terminate the

step when the load exceeds a certain magnitude.

6. Nodenumber at which the ﬁnishing displacement value is being monitored.

7. Degree of freedom being monitored.

8. Value of the total displacement(or rotation) at the node and degree of freedom that, if crossed

during an increment, ends the step at the current increment.
