3D磁场的模拟与分析
我是学焊接的,对磁场的东西不太懂,请大家指导下!3D的静态磁场好像是用标量法的,我用了96或98单元,然后设置铝的相对磁导率1.000022;空气相对磁导率1;铁的相对磁导率取636;磁体的相对磁导率为5.30504,矫顽力为150000。模型的数据为:
BLOCK,-0.025,0.025,-0.015,0.015,-0.001,0.001,
BLOCK,-0.025,0.025,-0.015,0.015,-0.001,-0.011,
BLOCK,-0.025,0.025,-0.015,0.015,0.001,0.011,
BLOCK,-0.025,0.025,-0.015,-0.017,-0.011,0.011,
BLOCK,-0.025,0.025,0.015,0.017,-0.011,0.011,
BLOCK,-0.025,-0.035,-0.03,0.03,-0.02,0.02,
后来有试着用远场单元47,可是不知道怎么用。
哎,反正最后的磁力线就是不闭合呀!请那位好心人帮我看一下怎么办,能做出来就更好了,谢谢! 远场单元47怎么划分网格呀?或者怎么加载边界条件啊? 你太专业了
看不懂 太专业 不懂 远场单元也应当是直接划分网格吧! 空气层没建对吧 LZ很深奥啊! 楼主一定要建立空气模型 然后为了减少模型的求解规模和提高计算精度 在外围添加远场单元
当然也可以把空气建的大一点 在边缘施加平行边界条件
96 97 98 117单元都可以计算三维静态磁场 只不过96 98 用标量位 97 117 用矢量位
