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） By ljc819514 

方案二：Ansoft Help 文档—“Coupling Maxwell Designs with ANSYS Thermal via Workbench” 19. To export the thermal result to Maxwell, right-click on the Imported Load (Maxwell2DSolution), or Imported Load(Maxwell3DSolution) and select Export Results. 20. To fully utilize the automation capabilities provided in ANSYS Workbench, select Imported Load (Maxwell2DSolution), or Imported Load(Maxwell3DSolution); and in its Detail window, select Yes for Export after Solve. With this option selected, users can continue the iteration between Maxwell/Thermal simulations from the Workbench schematic. To “push” the exported thermal results back to Maxwell, right-click on Maxwell's Solution cell on the Workbench schematic and select Enable Update. Then, right-click again on Maxwell's Solution cell and select Update. This will 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. By ljc819514
