Ansoft与Workbench协同仿真实现双向耦合的方法

在科研或者做研究生毕设的过程中，经常会遇到多个物理场的耦合问题，诸如流固耦合、热电耦合、磁热耦合以及磁热结构耦合等等。而且往往还会遇到各种非线性问题：磁导率是随温度变化的或者电阻率也与温度成非线性关系，这时为了保证计算结果的准确性，有必要也必须是多物理场实现双向耦合。
    在Ansoft与Workbench实现磁热耦合的过程中，就需要保证他们耦合式双向的。下面介绍两种方法：
方案一：利用Workbench组件系统中的“Feedback Iterator”模块，如下图

然后设置Feedback Iterator属性，也可添加脚本。

使用这种方法，通常3-4次耦合迭代即可达到稳定（Ansys官方说法）

方案二：Ansoft Help文档—“Coupling Maxwell Designs with ANSYSThermal via Workbench”

19. To export the thermal result to Maxwell,right-click on the Imported Load (Maxwell2DSolution), or Imported Load(Maxwell3DSolution)and select ExportResults.

20. To fully utilize the automationcapabilities provided in ANSYS Workbench, select Imported Load (Maxwell2DSolution),or ImportedLoad(Maxwell3DSolution); and in its Detailwin-dow, select Yesfor Export afterSolve. With this option selected, users can continue the itera-tionbetween Maxwell/Thermal simulations from the Workbench schematic.

To “push” the exported thermal resultsback to Maxwell, right-click on Maxwell's Solution cell on the Workbenchschematic and select Enable Update. Then, right-click again on Max-well's Solution cell and select Update. Thiswill trigger Maxwell to re-simulate its solution with thermal results.

To continue the solve iterations,repeat the following steps as needed:

a. Right-click on Thermal's Setup cell and select Refresh.

b. Right-click on Thermal's Setup cell and select Update.

c. Right-click on Maxwell's Solution cell and select Enable Update.

d. Right-click on Maxwell's Solution cell and select Update.
