How to increase the resolution of a geometry? (in my case a circle).

Hej,

I have a solid block where I want to substract a really small part from the top surface (tries to be a sagging of 20 um). I am using a the difference booelan operation to do it.

The volume to subract is a cylinder. My problem is that the cylinder is huge compared to the solid block. The circle (which I extrude to obtain the cylinder) is defined by a defined number of segments (or points).

In other software's there is the option to increase this number of points (segments) when defining a circle. I think it is called "resolution".

How can I do it in Comsol?

(I was also thinking about defining a parabolic curve and extrude it, will I have the same problem?

Thanks in advance.

Hi

you have only a "visulaisation" problem from my point of view, the surface is urved and cut away take a look

(I have meshed the device, solved for initial conditions in any physics and ploted "z" along Y for the curved edges)

Good luck
