Hello,

I am new in COMSOL and I was wondering if anyone could five me any idea. I want to simulate the evolution of the induced charge on a surface as the relative position to a charged object varies, this variation must be parametrized by the user and not due to the electrostatic effects. My first idea was to parametrize the position of one object as a function of time but i couldn't. Is possible to do it in any other way? Thank you very much in advance!

Gerard

Gerard,

you can parameterize the position of an object in a stationary study. You have to add a parametric sweep to the study and choose a range for the position parameter. This will generate the geometry and the mesh in each parameter loop.

Cheers

Hi

you can parametrise with a "global Parameter" that changes the geometry position and do a stationary analysis to see the charge distribution in ES, or you charge your system, and in EC with conduction you do a transient analysis to see how things decay by condition.

Else in steady state sinus excitation you have the frequency response versus given positions, ...
