| 如果理解的没错的话,楼主是2D模型吧。因为3D模型的切向定义不是单一的。MagNet目前还不能直接显示这两个量。但楼主可使用Add New Field 脚本工具,使用Bx和By计算径向和切向磁密。如下是计算径向的一个简单例子以供参考: 
 Set oBFieldx = Sol.getSystemField(oMesh, "B x") 'Get B x field
 Set oBFieldy = Sol.getSystemField(oMesh, "B y") 'Get B y field
 Set oBRadial = oBFieldx
 Set oBRadial2= oBFieldy
 
 Dim oFieldx, oFieldy, oATANField, oATANField2
 
 Set oFieldx = Sol.getSystemField(oMesh, "X") 'Get the field of X coordinates
 Set oFieldy = Sol.getSystemField(oMesh, "Y") 'Get the field of Y coordinates
 
 Set oATANField = oFieldy.atan(oFieldx) 'Get the angle
 ' where F1.atan(F2) in MagNet is equivalent to atan2(F1,F2) which is equal to atan(F1/F2) when F2 > 0
 Set oATANField2 = oATANField.clone()
 
 Call oATANField.cos() 'Converts field to the Cosine of its original values ; In other words the original OATANField gets overwritten with the resultant field
 Call oATANField2.sin() 'Converts field to the Sine of its original values
 
 Call oBRadial.multiply(oATANField) 'Bx*cos(angle)
 Call oBRadial2.multiply(oATANField2) 'By*sin(angle)
 
 Call oBRadial.add(oBRadial2) 'Bx*cos(angle) + By*sin(angle)
