Hello Fellows,

I need little help in version 4.2a.

If I for example have one sphere and one conus (there is some intersection between them of course) , how to made one object of these two objects? I want to make just one domain of these two domains.

I tried with union, but I can't solve it on that way.




Thank in advanced.

Hello,

Thank you for your help.

This is most simple example of that problem (block + sphere).

How of these two objects (domains) I can make one.

Regards,

Nikola

Nikola,

I'm not able to open your file, comsol says the " ... model is damaged or not valid".

Can you tell me your comsol's version? (the first line that appears in the message tab after opening comsol).

cheers,
