Hi guys,

I'm struggling to understand the syntax used in funkysetfields to accurately define different initial shapes of bubbles.

I am aware of the link https://openfoamwiki.net/index.php/C...funkySetFields and the presentations associated in it.

However I was wondering if someone could provide some guidance (links preferably) so that I can understand the syntax better (I'm sort of a beginner).

For example, the following synthax is for a spherically shape (pow(pos().x-0,2) + pow(pos().y-0,2) < pow((0.1E-3),2))

However, what would be the synthax for a quarter bubble with a wall below it.

Thanks for your help
