仿真时会提示错误：Mesh generation : minorsurface repair is required. More details will be available via Mesh Statisticswhen meshing is completed. (9:38:40 下午 四月 20, 2012) 我试着将旋转角度调小一些，文件如附件arc_match_0420.hfss所示。细节处如下图所示：
仿真仍然会有上面的提示，仿真结果基本相同，如下：
S参数看起来是好的，但是磁场分布表现为集中在微带线左端激励处，做一animate发现只有很少的能量传输到微带线里。请问是不是建模的思路是错误的？我试着将grid settings中的density设置为10pixels，但是好像没有什么改善。直接画弧形然后sweep得到的结果也没有区别。
不知道应该怎样建模使得激励处以及电容和微带线、介质板接触的地方贴合的精确，能量传输进微带线？
p.s. 文件中的fov是用来看磁场分布的

hi , please see the attachments. I'd like to simulate a conformal microstrip coil with hfss which resonates at 128MHz for MRI.
It is side fed and tuned and matched with lumped LRCs.
At first, the circuit is short seen from smith chart. I changed the grid settings and curved object visualization, elements in the model are mostly created using sweep and rotate. I have check the model carefully and its runs without warning.
However, it seems that the magnetic field results indicated that little energy had been transmitted into the p@tch, and most aggregated at the excitation part. I have tried meshing the tiny parts in the model but without improvement
.
The ideal magnetic field is what looks like in the attachment "desired magnetic field".
Could you please help me to see what's wrong with the model? or different model methods?
FYI, the file was created with hfss 13.0, and the dimensions of the p@tch are given for prostate MRI.
