*CONVC

Data format:

A single line with 5 parameters, as follows:

ITERM EPS1 EPS2 EPS3 EPS4

Status:

Optional and only if cable elements are used.

Purpose:

To define convergence criteria used within the cable interface pre-calculation stage.

Details :

Parameter	Description
ITERM	Maximum number of iterations for the calculation of the equilibrium configuration of an element. The standard value is 200.
EPS1	Criterion to check if a node is on the floor (Def = 1.e-05) Xlim = EPS1*Xlo
EPS2	Criterion convergence on forces for a cable laying on the floor : Glim = EPS2woXlo (Def = 1.e-04)
EPS3	Convergence criterion on displacements for the catenary equation : EPS3*Xlo (Def = 1.e-08)
EPS4	Convergence criterion on forces for the catenary equation EPS4*EA (Def = 1.e-08)
