Hi, everyone

I am only a beginner at comsol. I need help with making a half-circle.
I want to make a circle with two half-circle. However, in the geometry menu, there are circle and ellipse.
Can you explain to me how to make half-circle. Thank you.

Whenever I need a half-circle, I first create a full circle and then a rectangle that covers half of the circle, then form an intersection between the two.
