Moving Mesh: Linear front in circle

Hi all,

when i am using a moving mesh in a rectangle it works fine.

But at the moment i am trying to use a moving mesh/deform geometry in this way:

a linear boundary should move through a circle.
But the circle always deforms.

Does anybody ve an idea how realize that?

The very simple model is attached.

Thx.

Hi,

try to use "Form Assembly" instead of "Form Union" as the final geometry operation. Otherwise COMSOL does not know that the circle and beam are separate objects.
