How do I load arbitrary current to the coil in comsol?
In comsol, I want to give the coil arbitrary current defined by interpolation, but it always wrong. My specific approach is: (a) the global definition, using interpolation method defined excitation...

A yellow expression mostly means a unit issue. Using current3[A] should do the trick. Cheers Edgar -- Edgar J. Kaiserwww.emphys.com

Hi! Since you are doing a transient simulation, you should use current3(t). If you get unit error, you can write current3(t[1/s])[A]. Ralf

Thank you very much. You are right. In comsol, the functions need units. I want to ask another question. when 0=<t<=1, the function is f(t). When 1=<t<=2, the function is g(t). If f(t) and...

Hi! Try to define a third function like: h(t) = if(t<1, f(t), g(t)) Ralf

thank you. Your answer is right. I am doing eddy current detection. Do your research direction is the same one ? if it is, I hope that we can have more exchanges.

Excuse me. I want to ask another question. when 0=<t<=1, the function is f(t). When 1<t<=2, the function is g(t). When 2<t<=3, the function is h(t). How can the three functions be...

you can use Definitions -> functions -> piecewise in argument type "t", for "start" and "end" use the start and end times and in "functions" use the expression you want for this part
