I&#8217;m simulation an apple falling from a drop height of 2 meters under standard earth gravity. I want to simulate the deformation once the apple lands on the rigid surface.<\/p>\n<p>Here are some the challenges I&#8217;m facing:<\/p>\n<p>1. An apple is not a perfect sphere. How do I include some physical and mechanical properties of the apple e.g.<br \/>~Equatorial diameter<br \/>~Polar diameter<br \/>~Thickness<br \/>~Shape index<br \/>~Volume<br \/>~Curvature radius<\/p>\n<p>2. I assumed a perfect sphere for the initial simulations. However, the apple bounced off the rigid structural steel surface like a tennis ball would. How can I overcome this and effectively realize a simulation that depicts normal reaction of the apple in such a scenario<\/p>\n<p>3. Change in color depicts change in deformation to a varying extent. However, there is change before the apple hits the surface. What could be the issue and how can I overcome it.<\/p>\n","protected":false},"template":"","class_list":["post-358681","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["342103","240"],"_bbp_author_ip":["96.7.74.191"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["525"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["358681"],"_bbp_forum_id":["27814"],"_bbp_engagement":["240","342103"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["358693"],"_bbp_last_active_id":["358693"],"_bbp_last_active_time":["2024-03-24 20:23:07"]},"test":"ma1602736qu-edu-qa"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/358681","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\/358681\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=358681"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
