how to generate high quality mesh with this geometry?
 

Hi, I would like to ask how I can generate high quality mesh with this geometry? It is a building with window opeing at a very small distance. It is hard for me to generate acceptable mesh quality. Thank you

We need a lot more information : hexa or tetra ?
Show us what you have already tried, where you are stuck and then we could try to help you.

Hi BrolY, Thank you for the reply. I tried to generate structure mesh. But the angle will not meet the requirement. I tried to block in two ways. One is blocking it directly, the other one is to use Y-block at the wedge. But both of them cannot get acceptable angle for mesh. I enclosed two projects of the exercise. Thank you.

Is there anyway to combine structure mesh and unstructure mesh in ICEM? How can I realize it?

Can I get any suggestions for the problem?

there are no windows! you just have one part! so improve and adjust your geometry first

Hi energy382, I did the mesh again and please find it in attachment. I do not know how to handle with sharp agnle geometry if I would like to use block to generate structure mesh. Thank you.
