For 3-D mesh splitting, command-driven transition element control (ESEL) is not used. The program generates the transitions automatically.
4.3.2. Key Commands Used in Rezoning
Following is a description of key commands used in the rezoning process and provides supplemental information to the rezoning process flowcharts.

|
|
/CLEAR |
Clears the data- |
Always clear the database first, before reentering the solu- |
|
base |
tion processor (/SOLU) and starting the rezoning process. |
REZONE |
Initiates rezon- |
When you initiate rezoning, the program verifies that the |
|
ing |
necessary files (.rdb, .rst, .rxxx, and .ldhi) exist for |
|
|
the specified substep and rebuilds the data environment |
|
|
at that substep. |
|
|
All nodes are updated to the deformed geometry in |
|
|
preparation for remeshing. |
