Your expansion ratio in Figure 1 on the left side seems way too high. Make the expansion ratio go more smoothly.

In figure 3 that might also be the case at the boundary of the two sections. Also, I assume, that the angle of the element will not be good. Something may be off with one node or so.

Thank for helping me!

I am relatively new on ICEM

I tried, and this this happened, I don't know why...

Maybe, you need to search for some tutorials on ICEM to get a bit more familiar with the functions.

Could be association issue and also could be wrong method to create the blocking. Did you combine any vertices while creating the block?

Thank you for helping!

It was an association issue. The edges were automaticaly assossiated to the surfaces. I removed them, than it worked!!

Best wishes!
