各位好!
请教在COMSOL4中如何设置周期性边界条件?要自己写公式那种,例如在源端u,目的端 u*exp(i*G*a) 这种。
我在COMSOL官方提出了这个问题,里面有高手说可以用定义下面的模型耦合可以实现,但是我现在还实现不了,希望有人能实现的,指教下!
现贴出,给出的解答如下:
问题:
The first question is In COMSOL 3.5a, the periodic boundary condition can be express as u in the source and U*exp(i*k*a)in the destination, but it doesn't works in COMSOL4.
解答:
Hi,
in an effort to make the interface more clean and easy to use,
the periodic boundary conditions in 4.0 is used for pure periodic or antiperiodic conditions. What you outline can be done with a Model Coupling, found under Definitions. |
