Draw > Box
Position: (94,0,49)
Box尺寸:(XSize, YSize, ZSize)>(200,200,100) 重命名为:coil
按 E 键,将体选择改为边选择 选中coil模型的4个竖边, 将所选边缘圆滑化
Modeler > Fillet Fillet 参数设置: 1. Fillet Radius: 50mm 2. Setback Distance: 0mm 选中coil和coilhole模型
Modeler > Boolean > Subtract Blank Parts: coil Tool Parts: coilhole 得到coil模型如下: 将coil的材料改为copper
创建相对坐标系
Modeler > Coordinate System > Create >Relative CS > Offset 相对坐标偏置 X: 200, Y: 100, Z: 0
设置激励电流加载面 选中coil

创建计算区域(Region) Draw > Region
创建哑元Dummy
Dummy技术的优点:
只对所关心的局部区域进行加密剖分,提高该区域的计算精度,无需对整个区域进行加密,节约了计算资源。 将坐标系改为Global CS Draw > Box
Position: (-3,68,30)
Box尺寸:(XSize, YSize, ZSize)>(300,8,8) 重命名为:dummy 材料为真空
设置Dummy的剖分参数 选中Dummy
Maxwell > Mesh Operations > Assign > On Selection >Length Based. 不选Restrict Length of Elements 选中Restrict the Number of Elements Maximum Number of Elements:1000
Select the menu item Maxwell>Analysis Setup > Apply Mesh Operations
3.设置自适应计算参数(Create Analysis Setup) Maxwell 3D > Analysis Setup > Add Solution Setup
最大迭代次数: Maximum number of passes : 10 误差要求: Percent Error: 2%
每次迭代加密剖分单元比例: Refinement per Pass : 50%
设置激励源的频率 Solver > Adaptive Frequency: 200 Hz
