==Summary==

The module <code>ProblemTruss</code> contains a multi-objective optimization problem. It implements a simple Finite Element Analysis code for analysing a truss structure.

[[File:ProblemTruss.png|300px]]

The truss consists of 10 rods which connect the 6 point (labelled from 0 to 5). At point 0 and 2, a force F=45'000N is applied, which deforms the truss and generates stresses in the 10 rods.

The input of this module are the individual cross-sections of the rods (i.e. 10 cross-sections).

The output of this modules are 3 values, which can be set either as objectives or constraints:

# the weight of the 10 rods of the truss
# the maximum stress in a rod
# the maximum deflection of a node of the truss.
