EXAMPLE 1
Simply Supported Plate (Mismatched Meshing)
As illustrated in Figure 1, this is a model of a simply supported plate, which has been
modeled in two different ways. In one case the mesh is uniform across the plate and in
the other case the mesh is fine on one half of the plate and coarse on the other half of the
plate. In the latter case, an interpolating line constraint is automatically generated to
enforce displacement compatibility between the adjacent halves of the plate where the
mesh does mot match. As shown in the figure, correlation between the two models is
very good.
