In order to prevent this formulation from being activated, provide a small value for the material incompressibility parameter, d (e.g., use d = 0.001). This will prevent the mixed u-P formulation from being activated by the solver and your GPU will also be used in the solve as well.<\/p>\n","protected":false},"template":"","class_list":["post-165449","topic","type-topic","status-publish","hentry","topic-tag-4391","topic-tag-hyperelasticity","topic-tag-materials","topic-tag-mechanical","topic-tag-structural-mechanics"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["3\/15\/2023 20:20"],"_bbp_forum_id":["27814"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["778"],"siebel_km_number":["2054567"],"product_version":["19"],"km_published_date":["2018-05-19T00:00:00.000Z"],"family":["Structural Mechanics"],"application_name":["Mechanical"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/165449","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/165449\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=165449"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
