我用的是一个半径为2的铜线绕Z轴绕成圆柱形螺旋线.线圈的两头都连接电路。外面用的边界是Radiation,Solution type选择的是Terminal, 激励选择的是Lumped Port。当选用频率是1GHz时,软件正常运行.当选用频率是1MHz时,软件运行一段时间后出错.错误提示为:Port refinement, process abc3d: failed to solve the problem due to lack of precision. The likelycause is that the frequency is too low. 我需要的频率就是1MHz呀.请问高手,模型怎么改进,才能使软件正常运行起来呀?谢谢! 1.rar
