请教一下,关于电流加热的加载

clausewitz

我在做一个电流加热的温度场计算,除了要计算的模型,还有外电阻,外电阻在整个的计算过程中电阻是不变的,因此我要为加载的电压设定一个函数,请问怎么设置啊?
另一个问题,在模型的边界条件的设定上,由于外界温度是一个曲线,请问怎么设置?
希望各位能人不吝赐教!

You can use the Function Tool to apply complicated boundary conditions on a model. The Function Tool has two parts: the Function Editor creates an arbitrary equation or function (multiple equations), and a Function Loader retrieves the functions and loads them as TABLE arrays. They are then applied to a model using the tabular boundary condition process described in Applying Loads Using TABLE Type Array Parameters.

You must define your function and load it as a TABLE array before you try to add it as a load. You can access the Function Editor either via Utility Menu> Parameters> Functions> Define/Edit, or via Main Menu> Solution> Define Loads> Apply> Functions> Define/Edit. You can access the Function Loader either via Utility Menu> Parameters> Functions> Read from file, or via Main Menu> Solution> Define Loads> Apply> Functions> Read file
