Hello,
I am trying to mesh with ICEM a domain of a flow over a backward facing step but it doesn't work using Blocking. When I use Blocking my 2D domain is not closed. The upper and lower blocking lines continue on the right and left sides to infinity ???
The simple geometry is below. I think that it is an environment setting problem but I don't know which one.
Any suggestions.

I don't think that should be happening as long as you haven't changed the default settings on ICEM. Have you tried checking the 2D blocking mark in the blocking menu or manually highlighting the entities you are trying to block?

I have tried to reset the settings and marked Initialize with settings also in the Block menu. I am using 2D planar. So, I can not choose entities.

try using 3D blocking instead. I had a geometry similar to yours and using 3D blocking, never had a problem.

If you blank the part "VORFN", it should be good.

No. I did not blank the "VORFN" part just to show that I am missing a vetical line on the right side of my domain and the blocking is not closed on the right and the left sides (See the third picture attached)

It was the tolerance which were too big. I reduced the tolerances in Menu -> Settings -> Model
