\title Numerical Analysis of a 1-Dimensional
Immersed-Boundary Method\\
\abstract We present the numerical analysis of a simplified,
one-dimensional version
of Peskin's immersed boundary method, which has been used to
solve
the two- and three-dimensional Navier-Stokes equations in the
presence of immersed boundaries. We consider the heat
equation
in a finite domain with a moving source term.
We denote the solution as $u(x,t)$ and the location of the
source
term as $X(t)$. The source term is a moving delta function
whose strength is a function of u at the location of the
delta function.
The p.d.e. is coupled to an ordinary differential equation
whose
solution gives the location of the source term.
The o.d.e. is $X'(t) = u(X(t),t)$, which can be interpreted as
saying the source term moves at the local velocity.
The accuracy the numerical method of solution depends on how
the
delta function is discretized when the delta function is not
at
a grid point and on how the solution, u, is represented
at locations between grid points. We present results showing
the effect of different choices of spreading the source to
the grid and
of restricting the solution to the source location.
The problem we analyze is also similar to the Stefan problem
and
the immersed-boundary method has features in common with
particle-in-cell
methods.\\
