Hello everybody,<\/p>\n
<\/p>\n
I will try to explain briefly what is the problem I am facing. Basically, I have a model made up of 32 bodies and 4 different materials that can be used. I have to find which combination body-material guarantee the minimum compliance once fixed a target weight. It is a sort of topology optimization problem.<\/p>\n
<\/p>\n
I found this code that I am trying to use that seems could help me:<\/p>\n
<\/p>\n

\n! MATSWAP.MAC
\n! Created by Joe Woodward at PADT,Inc.
\n! Created on 2\/12\/2016
\n!
\n! Usage: Create Named Selections, Holder1, Holder2, etc.,for BODIES using the materials that you want to use.
\n! Create Named Selections called MatSwap1, MatSwap2, etc. for the groups of BODIES for which you want to swap materials.
\n! Set ARG1 equal to the Holder number that has the material to give to MatSwap1.
\n! Set ARG2 equal to the Holder number that has the material to give to MatSwap2.
\n! And so on....
\n! A value of 0 will not swap materials for that given group.
\n!
\n! Use as is. No Modification to this command snippet is necessary.

This code swap the material contained in a body “Holder” to the material Swap1,2,3 which number is the number of the ARG (input of the commands).<\/p>\n
<\/p>\n
THE PROBLEM IS: the number of arguments is limited to 9. There is a way that I can increase this number? If I use this command twice how can I modify this code in order to take the Swap10,11,12… during the second time the code is run?<\/p>\n
<\/p>\n
I wish I was clear…<\/p>\n
<\/p>\n
Thank you in advance to anyone who will help me!<\/p>\n","protected":false},"template":"","class_list":["post-28469","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["636"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["2801"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["28469"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","155284"],"_bbp_voice_count":["2"],"_bbp_reply_count":["10"],"_bbp_last_reply_id":["56032"],"_bbp_last_active_id":["56032"],"_bbp_last_active_time":["2018-01-07 16:27:36"]},"test":"gmtassi"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/28469","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/28469\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=28469"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
