circle

NAME

circle


SYNOPSIS

          circle x0 y0 r [-optional link arguments]


DESCRIPTION

circle creates a circular entity of immersed boundary points. circle requires three arguments. circle allows for optional link arguments by interpreting the following options. The default resting length is determined so the points are no more than a distance of h/2 apart. The default resting angle is determined so that the circle remains a circle if there is no fluid flow. The tether points are located at the initial IB point positions.


SEE ALSO

line, polygon, wheel


EXAMPLE

          circle 1.0 1.25 0.5 -b 10000
Forms a circle centered at (1,1.25) with a radius of 0.5 and increases the bending stiffness to 10000. The circumference of the circle is $\pi$, and the resting length is not specified so the number of immersed boundary points set by IBIS is $\lceil 2\pi/h \rceil$ and they are equally spaced on the circle.
