slink

NAME

slink

SYNOPSIS

          slink e1 e2 [-b break] [-l rest] [-s stiff]

DESCRIPTION

slink links a singlet, entity e1, with every immersed boundary point on another entity e2.

slink requires two arguments. These are;

• e1 - the name of the singlet.
• e2 - the name of the other linked entity.

To link two entities, they must each be named. Therefore, in the definition of those entities, the -N or -A flags must be used.

slink interpretes the following options.

• -b break = link breaking length(as a fraction of the initial length)
• -l rest = link resting length (as a fraction of the initial length)
• -s stiff = stiffness of the elastic springs

To use slink, e1 must be a singlet. The links are formed by the following method. Let x be the singlet point and let X_j be the jth point on entity e2. Then a link is formed from x to X_j for every point on e2.

EXAMPLE

          circle 0.25 1.25 0.05 -N 1 -n 100
          singlet 0.25 1.25 -t 10000 -N 2
          slink 1 2

This code establishes a ``wagon wheel'' of immersed boundary points that are tethered to the center of the circle.
