– Up to 3 three symmetry planes can be specified. – Full or partial models can be included in the Enclosure. – During the model transfer from DesignModeler to Simulation, the enclosure feature with symmetry planes forms two kinds of named selections:
– Winding Bodies: Used to represent wound coils for source excitation. The advantage of these bodies is that they are not 3D CAD objects, and hence simplify modeling/meshing of winding structures.

ANSYS电磁场分析例子
ANSYS电磁场分析例子我们将考虑一个简单的电磁场问题，即一个平行板电容器的电场分布。
这个问题可以很容易地通过ANSYS进行建模和求解。
首先，我们需要进行几何建模。
在ANSYS的建模界面中，我们可以使用几何建模工具来创建一个具有平行板结构的电容器。
我们可以定义平行板的尺寸、间距以及材料属性等。
接下来，我们需要定义边界条件。
在这个问题中，平行板上的电势是已知的。
我们可以在边界条件中指定平行板上的电势值，然后在求解过程中，ANSYS将根据这些边界条件计算电势分布。
然后，我们需要设置求解器选项。
ANSYS提供了多种求解器选项，包括有限元法、有限差分法等。
我们可以根据我们的具体问题选择合适的求解器。
接下来，我们需要应用材料属性。
我们可以在材料库中选择合适的材料，并将其应用于电容器的几何模型中，以便ANSYS可以根据这些材料属性计算电场分布。
最后，我们可以运行求解器并分析结果。
一旦求解器完成计算，我们可以在ANSYS的后处理界面中查看电场分布结果。
ANSYS提供了丰富的后处理工具，包括可视化和数据分析工具，可以帮助我们更好地理解和解释电场分布结果。
通过以上步骤，我们可以使用ANSYS进行电磁场分析，并得到电场分布结果。
根据这些结果，我们可以评估电容器的性能，例如电势分布、电场强度等。
这些信息对于设计和优化电容器以及解决其他电磁问题非常有价值。
总结起来，ANSYS电磁场分析是一种强大的工具，可以用于解决各种电磁问题。
通过几何建模、边界条件设置、求解器选项设置、应用材料属性和结果分析等步骤，我们可以使用ANSYS获得准确和可靠的电场分布结果，为问题的解决和优化提供有力支持。
