    Description

    A磁静力剂物体在方便绘制和后处理的形式中包含磁电势，磁场和磁通密度值。

    The magnetic potential, magnetic field, and magnetic flux density are calculated at the nodes of the triangular or tetrahedral mesh generated byGeneratemesh. Magnetic potential values at the nodes appear in theMagneticPotential财产。节点处的磁场值出现在MagneticField财产。节点处的磁通密度出现在磁性浮雕密度财产。

    To interpolate the magnetic potential, magnetic field, and magnetic flux density to a custom grid, such as the one specified by网格格里德, use theinterpolateMagneticPotential,间磁性菲尔德， 和螺型磁通弹功能。

    Creation

    使用solvefunction. This function returns a solution as a磁静力剂目的。
