Structure generation for free-form architectural design (subsec C2)

Irregular architectural shapes must posses certain geometry that can be achieved by geometry optimization. Even then geometry is so complex that a close connection between the mesh and the parametric generation of the structure requires specialized approaches in a CAD kernel that can cope with numerous unique parts in the structure. The paper presents such a connection between the mesh and the parametric generation with a CAD kernel for a selected structure generation. The use of the hierarchical level-of-detail for transfer to other CAD&CAM packages is implemented for further analyses.

Extension of the Bissell-Johnson plasma-sheath model for application to fusion-relevant and general plasmas (sec D)

The results of this computational model will extend the validity of the solution to both fusion-relevant and general plasmas. The author's approach is as follows: (i) Existing models are extended to the so-called finite-? case, (ii) the kernel is not approximated but calculated exactly, (iii) The basic hydrodynamic quantities like ion density, ion flux, directional energy and temperature are derived directly from the velocity distribution on a grid , (iv) Two types of results are obtained.

Synthesis of elementary product concepts based on knowledge twisting (subsec A1)

Knowledge twisting is defined as a kind of manipulation of Physics P/Structure S/Design D in order to achieve various Function(s) F. This paper presents a method in which prior synthesis of functional structure is not required for product concept. Empirical analysis has shown that the use of this method does not lead to a combinatorial explosion. The method is based on the chaining of physical laws and complementary basic schemata.

Function and functionality in the conceptual design process (subsec A2)

The product function matrix and their requests model has been generated that interrelates functions and technical systems. Functions are described in terms of parameters defined from physical laws. Winning parameters are derived from a set of parameters for each function thus they are of major importance and have the strongest impact on a given function. By the application of the product function matrix and their requests in the conceptual design process the designer can reexamine new ideas based on previously made products.

Product function matrix and its request model (subsec A2)

A developed model of the first structural shape of the matrix of product function and its requests model have been shown in practice. It relates functions of the product and its requests model, and technical systems that solve them. The technical systems and functions are related among themselves through correlations that fill the field of the matrix. The first structural shape of the product function matrix and its requests model for the stator of the electrical motor of the intake unit have been generated through the prototype computer system.
