Designers often want to analyze more and more sophisticated structures, thus leading to very large "nite element models (typically 10 00 000 degrees of freedom for a body car, for example). These models being too costly for the early stages of design and optimization can be reduced by a substructure

Finite element modelling of processes, where geometry of the component evolves with time, usually involves checks/computations for contact between objects. Examples of these kinds of processes are sheet forming, bulk forming (forging, extrusion, rolling), etc. In some cases, it may be acceptable not
## Abstract A computationally efficient methodology is presented for the finite element modeling of thin conducting wires of diameter comparable with or smaller than the numerical grid size. The proposed model relies upon the insertion of lumped circuit elements at element edges along the wire axis
