磁铁棒如何设定？

FEKO还是不太适合除了这类问题，试试看HFSS或者CST

哦，已经建好了模型。舍不得重新来啊呵呵，我想把磁导率改大一些 不知道能不能模拟磁棒。

可使用 VEP 來求解..
Volume Equivalence Principle (VEP)
http://www.feko.info/product-detail/numerical_methods/mom/MoM_FEKO_6_1
The VEP allows the creation of arbitrarily shaped dielectric bodies using tetrahedral volume elements. More basis functions are typically required than for the SEP, but neighboring tetrahedra may have differing electric and magnetic properties.

The most common full-wave EM methods are the Method of Moments (MoM), the Finite Difference Time Domain (FDTD) method, and the Finite Element Method (FEM).  The MoM computation is done by discretising the surface current in the frequency domain, the FEM computation involves the discretisation of the E field in the frequency domain and the FDTD computation is performed in the time domain, discretising both the E and H fields [1].
FEKO is a powerful MoM solver which incorporates piecewise triangular functions for metallic wires and surfaces.  It employs Green’s functions as well as surface and volume equivalence principles (SEP and VEP) for dielectric volumes [2].  FEKO has been successfully used in a number of MRI radio frequency (RF) coil designs and magnetic resonance (MR) RF safety analyses [3,4,5,6,7].  Several MR applications will be discussed in further detail below.

真是好东西，正在学习中。

我也在做螺旋线圈中加入磁棒的仿真，可以交流下啊！我的QQ，59839248
