现在 COMSOL Multiphysics® 中对时域问题的处理大多数通过离散时间来处理,比如微波炉中加热一杯水,杯壁由两半不同介电常数的玻璃组成,杯子在托盘带动下旋转,对杯子中的水进行受热分析。传统的解法是将要分析的过程离散为一定步长的时间点,每算完一个时间点将杯子旋转一定的角度,然后在求解器中设置此次计算结果作为下一个时间点的初值。如果时间步长足够短,便可以模拟水的受热情况。这种做法的不足之处是需要调用 MATLAB 联合求解,计算时间较长。而且还有一个问题是在不同的时间点,由于场分布不同,杯子的位置不同,COMSOL 中剖分的网格应该是不同的 ... Mehr lesen
3D-modeling of magnetic components with FEM is challenging due to the involved nonlinearities and coupling effects between different physical domains. A specific issue is the consideration of lamination due to the high resulting element count for thin layers. Therefore, several ... Mehr lesen
