We will keep the default values and go to Billet window (See Figure 7a). Billet mesh can be
generated inside the template/wizard (brick mesh) or user can import a 3D-keyword file to read
in the mesh. For this lab we will generate the billet using wizard. A new feature has been added
to this wizard (only QT interface and not to Motif) which allows user to load material from a
"deform material library". Till now the only way to input material was from a user-keyword-file
"USER_HT.KEY". If you choose to load the material from material library then at the time of
Master file generation the wizard will also generate "CogBilMaterial.KEY" for billet material. A
similar provision has been made for Dies and Manipulators. Users still need to have
USER_HT.KEY in their problem directory because it is read in at each operation. Main purpose
of this is to provide user with certain action keyword reading facility. If you want to use all the
material data from the material library and do not need any action keywords at any particular
operation then just provide empty USER_HT.KEY in the problem directory. For this current lab
we will use the User keyword option for billet material. Copy the USER_HT.KEY to your
problem directory from the "labs" directory.
In the Billet Geometry window (See Figure 7b), choose the round cornered rectangle as the
cross section and enter a height/width of 20, a length of 60 and a corner radius of 2. Go to the
Billet Mesh window (See Figure 7c) and enter 100 for the number of mesh elements, 1 for the
size ratio and 14 for the number of layers. Click on the Generate Mesh button. Put 25000 for
remeshing number of elements. This number will be used to generate tetrahedral mesh in case
brick remeshing fails because of too much distortion.
