This project proposes the application of a Spline or more precisely NURBS-based finite element approach for the simulation of electrical machines, the so-called isogeometric analysis. This novel approach promises accurate solutions with a low number of degrees of freedom and enables elegantly to model geometry variations due to the Spline parametrisation, e.g. within an uncertainty quantification or shape optimisation of a machine. The movement of the rotor is implemented by mortaring in a saddle-point formulation. We propose novel approaches based on Splines and spectral elements which will be analyzed theoretically and practically.

该项目提出了一种基于Spline或更准确地基于NURBS的有限元方法来模拟电机，即所谓的等距分析。这种新颖的方法以较低的自由度保证了精确的解决方案，并能够优雅地模拟由于样条线参数化而导致的几何变化，例如在机器的不确定量化或形状优化范围内。转子的运动是通过鞍点公式中的迫击炮来实现的。我们提出了基于样条法和谱元的新方法，并对其进行了理论和实践分析。
