Hi Everyone,

Could you please help me to draw and to mention a box filled with air? i need to create it to measre stray inductance of a semiconductor module.

Thanks.

Hi

simply add a geometry "box"=cube of the desired size centred on your geometrical model.

if it is for magnetism, consider also a sphere, you have less "edge/vertex effects on the field lines

Good luck

Hi,
Could you please tell me again, how could i make the air fill box invisible in subdomain mode and boundary mode that has been shown in the example of AC/DC-- a. bond wire to a chip and b. power inductor where, i could see the bounday of the air filled box.


Thank you.

Hi,

In any boundary or subdomain you can deactivate it by unchecking the "active in this domain" check box.

Hi Suzan,
Thanks. if you look at those example that i mentioned, you will see all domain are in active mode but there are not visible.

See if there is a "wireframe rendering" option at the top of the Graphics Pane. That should make the box invisible but still show the boundaries.
