                       Abstract

Come is a software project focusing on object-oriented solutions for
implementing a framework for solving systems of partial differential
equations (PDEs) numerically. The scope is coupled multi-dimensional
equations, with high demands on the expressiveness and flexibility as
well as on the efficiency of the implementation. It is demonstrated
how a program solving the incompressible Navier--Stokes equations was
composed in a plug-and-play manner within the framework. The framework
encompasses explicit and implicit time stepping methods. A coherent
approach for boundary conditions and initial conditions is
presented. The use of object-oriented methodologies is stressed, and
it is noted that not only the object model, but also tools from the
dynamic model---such as scenario diagrams---have provided significant
contributions.
