Hello.

I want to sweep voltage in simulation.

Could you tell me how to sweep the voltage?

In attached file, you can see how I sweep voltage.

Hi

you have the internal parametric sweep see the solver node page : "Continuation" tab (hidden by default).

THen you have the external Parametric sweep if you want also to change the geoemtry with a sweep parameter

Good luck

Hello Mr.Ivar.

I can't find solver node. Where is it?

Hi

follow the arrows, in 6 steps it's done, but "Param" MUST be defined first as a Model "PARAMETER" (you can call it something else)

check the doc (note call your local COMSOL rep to find out how to get the updated version 4.1 as 4.0 is an early version and many things are far more difficult to do in this early version" The doc is also much better in 4.1

Thank you. Mr. Ivar

I read your advise.But I have question.

1)How can I sweep parameter like this (example 1>10 then 10>1 in one simulation)

Hi

sweep parameters can only be monotonously increasing, or decreasing, only limitation,
For your case you need a double nested parametric sweep, and that is not yet very well implemented in v4.0, works almost OK in 4.1 ;)

Check the doc

Thank you Mr.Ivar.

So, I'll do my simulation in Ver.4.1
