In principal, the calculation of the magnetic state inside a magnetic object requires the evaluation of the field in the entire unbounded space. With finite element methods restricted to finite domains, commonly auxiliary domains are employed which result in a non-physical cut-off. Not only are these additional domains result in an increased number of degrees of freedom which are strictly ...

Fluid flow in a cylindrical pipe needs to be characterized for various applications. The flow tends to form vortexes or becomes turbulent owing to many factors like inlet angle, inlet velocity, protrusions in the path of flow, etc. This work focuses on studying the characteristic behavior of flow inside a cylindrical pipe with non-laminar flow. It also aims at achieving laminar flow and studies ...

The modelling of a ferrite material is conventionally carried out using the Polder permeability tensor which assumes that the ferrite is saturated by a uniform magnetic field. This assumption is often inaccurate due to the constraints imposed by boundary conditions which renders the magnetic field non-uniform. This work proposes to overcome this by determining the magnetic field through a ...

Within the field of hot metal bulk forming the demand arises for fully three-dimensionally tailored properties at the microstructural level, nevertheless, reaching a predefined geometry with such tailored properties puts high requirements on the control mechanisms utilized in the process chain for combined heating, metal forming, and cooling processes. A simulation based rapid control ...
