How to make blockMesh file of this mesh?
 

Hi, everyone, I run into a problem of making blockMeshDict file of such a mesh in attachement:

In fact, the edge between point 17 and 8 should be a arc, but hard to draw it, I draw a line indeed.

PS: I split the whole block into 3 sub-blocks along Z-axis, and those red dash lines show the edge of each sub-blocks.
How to make the correct blockMeshDict file of this mesh or any better way to split the whole block?
Thanks!

Maybe you can follow the blockMeshDict.m4 inside the MRFSimpleFoam tutorial.
You have to write a .m4 file and run it to obtain the blockMeshDict.

.m4 file?
I'll check it ASAP.

Thanks!
