Just put a half sphere as initial droplet. does it work for you?

Bacha Munir

Thanks for your reply. When I put my sphere inside the rectangle, I cannot take the difference between them. Means, the sphere is not visible. Why?. Please, if you upload an mph file will be great.

first plot the system (schematic) you want to model in COMSOL by hand and send me.

the system is very big one, I am uploading the geometry. please, have a look. Thanks. see the attachment.

your model seems correct

there are a rectangular channel with a sphere.

what do you need more?

I cannot see the sphere inside the rectangle in my model.

Thank you so much. I got it. I understand now.
