Initial condition I&#8217;ve given force on back surface of bullet.<\/p>\n<p>In solution information I&#8217;ve given directional velocity. After solving I&#8217;ve got results which is uniform velocity upto 1sec.<\/p>\n<p>My doubt is Once the bullet reaches max velocity It has to drop down., To find this out should I increase the analysis time step ( If I increase the time, the computtaional time taken is very very long ). Can someone please help if am doing anything wrong here.<\/p>\n","protected":false},"template":"","class_list":["post-359785","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["342638","88","273386","342910"],"_bbp_author_ip":["96.7.218.215"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["362"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["359785"],"_bbp_forum_id":["27814"],"_bbp_engagement":["88","273386","342638"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["360423"],"_bbp_last_active_id":["360423"],"_bbp_last_active_time":["2024-04-04 07:47:48"]},"test":"venkyvenkatesh374gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/359785","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\/359785\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=359785"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
