it is possible to apply changes to certain areas, so called morph areas,
by moving the nodes of these morph areas. This can be used, for example, to
automatically generate several model variants and submit analysis runs
for these models. Further it allows to study the simultaneous influence
of changes in the morph areas on certain design responses defining the
quality of the design. These design responses are normally used to formulate
optimization targets and constraints. Based on these quality criteria
an optimum start design for a subsequent local shape optimization can
be derived. Note, morphing is a new feature within <span class = "ph">Tosca Structure</span>
