form-finding Workshop

winter semester 2020/21
event number | C-2.1-33/34
supervision | Prof. Dr.-Ing. Julian Lienhard
research associate | M.Sc. Seyed Mobin Moussavi
Force and geometry are the two critical factors in the implementation of load bearing structures. Alongside functional and aesthetic considerations, they are of major importance during the design process. Form finding is extremely common strategy in engineering design to discover utility-maximizing solutions to a set of constrains.
Aim of the workshop is to provide brief overview on different form-finding and simulation methods and introduce an interactive form finding tool. The brief overview of the mathematical background enables the participants to understand and evaluate the applicability and limits of each method.
The general focus of the workshop will be on the Finite Element Method (FEM), used as a tool of choice for a wide variety of engineering problems. FEM integrates material properties, external forces within the digital model to not only predict the designed structure behavior in real conditions, but also informs designers how the structure can be materialized.
Although most FEM tools requires structural background and have inconvenient workflow, Kiwi3D enables the integration of Isogeometric Analysis (IGA) into the CAD environment and thus creates a smooth and mutual exchange of design and analysis data. This tool represents the whole sequence of construction stages during the design process, without losing or having to approximate stresses or displacements, enable a detailed evaluation and enhanced design.
The Form fining process will be presented and applied in an interactive dialogue between tutors and students. The aim of the workshop to structurally simulate and analyze given projects, which can be design project students or an existing structure. The theory and introduction of the tool will be presented by M. Sc Philipp Längst, and TWE team will provide assistance in modelling, scripting and calculation theories.
As result of the workshop, students have opportunity to achieve supplementary credits by submitting a handout project. A complete and elaborate description of the handout including material, structure, methods should be illustrated and substantiated using sketches, drawings, diagrams and 3d digital model.
