Dont use this method, this method is used for making the internal wall. You just need to change the material and you will get the mesh on hemisphere.

Lightbulb I learn to feel the ICEM

I guess, now I am feeling the ICEM from heart. For example in this case if you snap the outer block first and then inner block, you will get the mesh problems as I have stated previously. You have to...

Thumbs up Done

Ok , got it. Nevertheless, we still make the hemishpere as hollow since fluid is not going inside.

In this case the far feild on the other side should be rectangular in shape to ease the meshing.

No, It is not true. You must have activated solid part. I was talking about the general mesh shape otherwise quality is good and angle is higher than 40.

I guess we are on different track. I guess...
