I have a .e exodus file that I would like to redefine the mesh points and mesh elements. Is there a way to decompose the existing mesh and remake it as a new cubit mesh?
Hi @tdoggwise,
yes it is possible to decompose a existing mesh somehow.
You will need to import the mesh with the mesh geometry option.
On import cubit will then create a mesh based geometry. You can check that in the geometry engine property.
After deleting the mesh you will need to set the developer commands on.
set developer on
You can try to decompose the volume with webcuts. Please note that not all webcuts and geometry operations will work for mesh based geometry. After decomposing you can imprint and merge the volumes and mesh them.
#!cubit
reset
create cylinder radius 1 height 5
mesh vol 1
block 1 add vol 1
set exodus netcdf4 off
set large exodus file on
export mesh "C:/Users/offic/Desktop/Cubit/test.e" overwrite
reset
import mesh geometry "C:/Users/offic/Desktop/Cubit/test.e" feature_angle 135.00 merge
delete mesh
set developer on
webcut volume all with plane xplane offset 0
webcut volume all with plane yplane offset 0
imprint vol all
merge vol all
mesh vol all
block 1 add vol all
