Re:请教Maxwell sv 版本中,关于边界条件的一个问题~~~
关于设定Balloon Boundary,Ansoft 提供的教程如是说:
In cartesian (XY) models, all outer edges may be defined as boundaries. However, in axisymmetric (RZ) models, the left edge of the problem region cannot be assigned a boundary condition. Because the solenoid model is axisymmetric (representing the cross-section of a device that is revolved 360 degrees around its central axis), the simulator ignores the balloon boundary you defined on the left edge of the geometry. Instead, it automatically imposes a different boundary condition, in order to model that left edge as an axis of rotational symmetry.
似乎,对Background 设定Balloon条件时,在XY Plance条件下,四边边界都生效,在 RZ Plance条件下,三条边界生效,坐边界自动忽略。由此看来,似乎不需要特别设定坐边界嘛? |
