本文摘要（由AI生成）：

本文介绍了三个模块的更新点，包括Adaptive time-stepping for nonlinear simulations等功能的更新，Twin Builder模块的Reduced Order Model和Modelica Editor的增强功能，以及Granta模块中Granta Materials Library和Granta Producer Materials Library的更新内容。这些更新旨在提升仿真效率和精度，增强用户体验，并增加新的材料记录和属性，以满足更多实际应用需求。

Ansys 2023已经发布好几个月了，其实发布不久我就安装了，但是因为那时候想着官方宣讲反正也快了，就干脆直摆烂等官方资料出来了再针对性地体验一下。不过几个月过去了，国外的宣讲才刚结束，国内的宣讲拖拖拉拉也一直没出来。我倒是坐得住，群里的小伙伴不干了。好吧，是谁嚷嚷着要我讲新功能的，我这就满足你们。

Ansys Aedt2023版本在全线产品上都有明显的更新，因为我平时不会用到全部的模块所以不会全部详细展开。这里我就先把所有模块的新功能摆出来，感兴趣的可以拉到文末仔细看一下。
从这篇文章开始我会针对maxwell的新功能进行深度体验然后分享体验感受和新功能的使用方法。

Windings in magnetostatic

静态分析中支持绕组设置

Winding也就是绕组，这个概念在maxwell中非常常见，与之相匹配的是coil线圈。Maxwell中，通过对coil和winding的搭配使用可以一定程度上模拟导体的电气连接关系，从而避免了外电路的使用。一般来说，每个winding中可以包含一个或多个coil来模拟多线圈的绕组形式。但是在之前的版本中，涡流场和瞬态场的激励全都支持coil单独添加激励和使用winding来添加激励的功能（图1和图2）。而唯独静磁场中，只能使用Coil而不能使用winding，也就不能通过设置绕组来设置电压或者电流型激励。

图1 涡流场中的激励

图2 瞬态场中的激励

而现在，2023版本中，在二维和三维的静磁场求解器中都可以支持winding的设置了，也就同样支持使用winding来设置电压或者电流型激励。

添加winding的办法与涡流场和瞬态场是相同的，首先定义好Coil Ternimal（图3），然后在模型树的激励上右键-点击Add winding来添加一个绕组（图4），然后在刚才定义的Coil Terminal上右键-Add to Winding（图5），就可以把线圈添加到绕组中了。线圈类型同时支持绞线圈和实体线圈（图6）。

官方给出了这样的一个功能测试结果。

一条磁路上有六个线圈，分别使用涡流场和静磁场设置好winding，涡流场的频率给0.1Hz来等效成一个静磁场，然后进行计算，计算结果显示，使用涡流场计算得到的磁场结果与静态计算完全一致。

感受：虽然大多数产品的工作状态几乎都不会使用静态场来分析，但是静态场作为一个复杂分析的试探性计算还是有些参考价值的，或者可以作为产品分析的初步性能校核。所以总的感受是，这算一个中规中矩的更新吧。

感兴趣的小伙伴，快来自己感受一下吧。如果你也在用最新版本，如果你也发现了功能的更新点，可以在留言中告诉我，我会放在这个系列中一一讲解演示。
