How can I create a mesh in Prepomax, similar to the one in the reference image?
I’ve tried several configurations, and I haven’t been able to get close.
Thanks

This part is very thin, don’t you want to use shell elements for it ? With solids, you could use the Extrude technique, but it doesn’t support the Quasi-structured quad 2D algorithm which can provide nicely structured meshes. Surface model (for use with shell elements) may let you do that if you partition the surface properly. There’s also the Transfinite technique, but it requires volume with 5 or 6 faces having 3 or 4 edges each so you would need to partition your solid. Other Gmsh techniques (including Shell Gmsh) also use the transfinite approach to generate mapped meshes for 3- and 4-sided faces.
Not as so coarse, but you can use either shell as it stands or 3d elements if you “thicknen” the shells.
As Jakub said, the key idea is first to split your model into elementary surfaces/volumes

hi, i’m experimenting different mesh setup and results below. It seems hole size are too small compared to edge length of part dimensions, need some partition by circle offset for largening.
model 2d extracted from original
2D meshing Frontal Delaunay for quads, Recombine: Blossom full-quad
2D meshing Packing of parallelogram, Recombine: Blossom full-quad
2D meshing Quasi structured quad, Recombine: None
later approach and algorithm used only for 2D model of shell and generated solid by normal extrusion, another two of them can be used for solid model as your original files.

may i know what mesher you use? it’s remembering me to achieve something like these patterns by many partitions to generate less skews type of distorted element.
