I want to apply an impulse force obtained from a Maxwell 2D transient analysis to the object. Figure-1 shows the diagram of force changes in terms of time (black curve). Since I have not found a way to apply this force, I have approximated it as a red curve. That is, the extremum points are connected linearly.<br \/>Importing force to the mechanical environment is done through Maxwell&#8217;s direct link. 4-time steps are defined so that in each of them, the value of one of the force extremums is applied, then by ramping them, the said linear curve is obtained.<br \/>But, I could not apply a ramp with a negative slope to the force, and ramping is done only in an upward direction. Figure-2 shows the final state of the force curve, which is different from the desired one.&nbsp;<br \/>Can someone please guide me to fix this problem?<img decoding=\"async\" title=\"Figure-1\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/12\/27-12-2022-1672154091-Screenshot 2022-12-26 220014.png\" alt=\"\"><img decoding=\"async\" title=\"Figure-2\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/12\/27-12-2022-1672154150-Screenshot 2022-12-26 215948.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-244920","topic","type-topic","status-closed","hentry","topic-tag-mechanical","topic-tag-transient-structural"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["171140","200","4413"],"_bbp_author_ip":["23.44.170.61"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1586"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["244920"],"_bbp_forum_id":["27791"],"_bbp_engagement":["200","4413","171140"],"_bbp_voice_count":["3"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["245197"],"_bbp_last_active_id":["245197"],"_bbp_last_active_time":["2022-12-30 18:31:05"]},"test":"hiwaghaffari"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/244920","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\/244920\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=244920"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
