Hi
I'm beginner in AC/DC module,so i read COMSOL documentation but it's not so clear for understanding what could i do for building an electrical circuit.
I want some information about simulation of electrical circuit,please help me.
thanks for your attention.

Hi
I have also noticed it is not much presented in the doc, but basically you need to draw your circuit by hand on a piece of paper, number the nodes 1,2,3 ... (0 is by default - and leave it so - the GND) and then enter your items into COMSOL und using your sketch node numbers to connect it up. The link to a physics FEM model requires the right hand click and interfaces for voltage or curent.
There are a few model library examples with simple circuits to drive an ACDC model (I have often used them for capacitive discharge circuits driving Joule effect MEMS, or small coils, it wors nicely.
If you have a complex circuit, use one of the other SPICE programmes and export/import your model

Good luck
