*findattachedelementfaces

Returns information to a table about solid elements attached to quad/tria element. The table must be created with 6 integer columns using the *tablecreate command. The output to each column is as follows:

1. Input element IDs
2. Attached element IDs
3. Attached element face IDs
4. Attached element configs
5. Input element collector IDs
6. Input element normal reversed flags

To find the elements attached to elements 12 and 13:

*createstringarray 6 int int int int int int
*tablecreate "attachedelementtable" 1 1 1 6
set table_id  [hm_getvalue tables name=attachedelementtable dataname=id]
*createmark elems 1 all
*findattachedelementfaces 1 $table_id
#Use hm_getvalue to query the table data:
set elemList [hm_getvalue tables id=$table_id dataname=cellvalue COLUMN=0]
set elemAttachedList [hm_getvalue tables id=$table_id dataname=cellvalue COLUMN=1]
set elemFaceList [hm_getvalue tables id=$table_id dataname=cellvalue COLUMN=2]   
set elemConfigList [hm_getvalue tables id=$table_id dataname=cellvalue COLUMN=3] 
set elelColList [hm_getvalue tables id=$table_id dataname=cellvalue COLUMN=4]
set elemRevNormalList [hm_getvalue tables id=$table_id dataname=cellvalue COLUMN=5]

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
