In this paper it will be explained how to create the geometry and the
mesh needed for a 3D simulation with FeatFlow. Up to now, there are
two separate ways: a semi-automatic and a manual fashion. On a midterm
range FeatFlow/Devisor interfaces to professional CAD and grid
generation software will probably become available such that there
will be a third and, simultaneously, more convenient way of 3D
preprocessing. But currently you only have the choice between two
possibilities. In most cases the problem`s geometry determines which
path to follow.
