Abstract
In this paper we propose a method to approximate flow problems in moving domains using
always a given grid for the spatial discretization, and therefore the formulation to be presented
falls within the category of fixed-grid methods. Even though the imposition of boundary conditions
is a key ingredient that is very often used to classify the fixed-grid method, our approach can be
applied together with any technique to impose approximately boundary conditions, although we
also describe the one we actually favor. Our main concern is to properly account for the advection
of information as the domain boundary evolves. To achieve this, we use an arbitrary Lagrangian-
Eulerian framework, the distinctive feature being that at each time step results are projected onto a
fixed, background mesh, that is where the problem is actually solved.
