N2 - This contribution will give a brief overview of isogeometric analysis (IGA) and its requirements and challenges. The smooth basis functions and the seamless link to CAD provide a lot of possibilities in the design of structures. Especially for lightweight structures, where form and force are highly interacting, this direct link is beneficial. Geometric design and mechanical properties are available in the same environment and can be manipulated simultaneously in order to optimize the shape and stress distribution in the final state of equilibrium. Furthermore, inverse methods can easily be used in order to design the mounted structure. Forward-analysis, such as a simulation of the mounting, has only to be considered in the second step to compute potential normal forces. This can be applied to lightweight structures, e.g. bending-active structures, tensile membranes, prestressed cable nets and combinations of those structures.
