BULK_UNSUPPORTED_CARDS & tcl script ?

Yes, it is possible. Here are some snippets to read/write to the BULG_UNSUPPORTED_CARDS. Just a disclaimer, haven't try all the code below.

check that the card exists.

 set cards [ hm_entitylist cards name ]
 set exists [ lsearch $cards 'BULK_UNSUPPORTED_CARDS' ]
 if {$exists != '' } {
     puts stdout 'BULK_UNSUPPORTED_CARDS exists'
 }

if it does not exists, you need to create it...

 *cardcreate 'BULK_UNSUPPORTED_CARDS'

To get the names of the cards, see http://www.altairhyperworks.com/(S(3fu2zyrlbyi03xcofiue25jd))/hwhelp/Altair/hw11.0/help/hwd/hwd.htm?control_cards.htm

Get the number of unsupported cards 

 set numOfUnsupportedCards [ hm_getentityvalue cards 'BULK_UNSUPPORTED_CARDS' '\$Bulk_NumUnsupportedCards' 0 ]

then you loop thru all the lines that the card have

 for { set i 1 } { $i <= $numOfUnsupportedCards } { incr i } {
      set line [ hm_attributearrayvalue cards BULK_UNSUPPORTED_CARDS Bulk_UnsupportedCards $i ]
      # you may want to append to a list;
 }

to write to the card, you need to tell HM how many unsupported cards you have as an integer attribute update and also, you need to update a string array attribute of the card. It think is as follows

 set bulk_unsupported_id [ hm_getentityvalue cards 'BULK_UNSUPPORTED_CARDS' id 0 -byname ]
 set num_unsupported_lines [ llength $data_list ]
 *attributeupdateint cards $bulk_unsupported_id 4080 1 0 0 $num_unsupported_lines
 eval *createstringarray $num_unsupported_lines $data_list
 *attributeupdatestringarray cards $bulk_unsupported_id 4081 1 2 0 1 $num_unsupported_lines

the list data_list includes the data you want to add to the unsupported card.

Hope this help. Some time a Altair AE explained me how to edit the cards. Aren't the Altair AE awesome?

Thank you so much, cesar.rivas !
