i am now studying on the simulation of stamping process by “DynaForm”, which uses an Orthogonal style mesh, the main area is quadrilateral mesh, and triangular/quadrilateral mixed mesh on the boundary. and there is chordal deviation control and angle control on the boundary mesh.

i just want to know can coreform cubit generate such style mesh? i want to use coreform cubit to do the mesh.

Hi @simxpert,
this mesh style is not supported.

Standard scheme would probably be triprim.

You could achieve something similar by decomposing the geometry into rectangles and triangles.

#!cubit
reset
create surface rectangle width 1 height 1.5 zplane 
move surface 1  x 0.5 y 0.75
tweak vertex 2  chamfer radius 0.8 
tweak vertex 5 6  fillet radius 1


#!python

n = 20
m = 30

for i in range (n):
 cubit.cmd(f"webcut body all with plane xplane offset {1/n*i}")
for i in range (m):
 cubit.cmd(f"webcut body all with plane yplane offset {1.5/m*i}")

#!cubit
imprint body all
merge body all
block 1 add surface all
surface all size 10

#!python
surface_list=cubit.parse_cubit_list("surface","all")

for sid in surface_list:
 vertex_list = cubit.get_relatives("surface" , sid, "vertex" )
 if len(vertex_list)==3:
  cubit.cmd(f"surface {sid} scheme trimesh")
  cubit.cmd(f"mesh surface {sid}")
  
#!cubit
mesh surface all
