Creation of Wedge Elements

Coreform Cubit Version: 2023.4
Platform: Windows 11

Issue
I wish to create wedge elements in a box element. I have meshed 4 surfaces with submap scheme and 2 surface with trimesh scheme. I tried to do volume meshing but it failed. How can I achieve a mesh with only wedge elements.

brick x 500 y 100 z 100
surface 1 2 3 5 submap smooth off
surface 1 2 3 5 scheme submap
surface 4 6 scheme trimesh
mesh surface all
mesh volume 1

Thanks,
Gaurav

I solved this problem using the following method,

brick x 500 y 100 z 100
surface 6 scheme trimesh
mesh surface 6
mesh volume 1
