I want to proceed in this manner: 0.1s, 0.2s, 0.3s, 0.4s, 0.5s, 0.6s, 0.7s, 0.8s, 0.85s, 0.9s, 0.95s, 1s. The total load substeps are 12, but the time period is not even. I am doing this since the analysis is resulting in high element distortion error after 0.8s, therefore after this time substep, I want to apply the load more slowly. <\/p>\n<p>The corresponding scale for pressure is: 0.878, 1.756, 2.634, 3.512, 4.39, 5.268, 6.146, 7.024, 7.463, 7.902, 8.341, 8.78. I inputted these scale factors in the Scale column and inputted the time as already mentioned under the Analysis Time (s) column. Source Time (s) is kept as 0 for all the steps.<\/p>\n<p>I was trying to use these step controls; Number of Steps = 1, Current Step Number = 1, Step End Time = 1, Auto Time Stepping = OFF, Number of Substeps = 12. <\/p>\n<p>I was expecting the analysis to being with time substep = 0.1 sec since I have manually entered it, with a pressure scale factor of 0.878, but unfortunately the time began at 0.0833 sec i.e. 1\/12 sec. The analysis actually ignored by manual entering of the time substeps and the corresponding CFX pressure scale factors, and an even time substeps began to be used by the solver. I am confused why is this happening and how can make the analysis work in the manner I want it to.<\/p>\n","protected":false},"template":"","class_list":["post-161857","topic","type-topic","status-closed","hentry","topic-tag-load-step","topic-tag-substep-2","topic-tag-time-step"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2919"],"_bbp_likes_count":["0"],"_bbp_subscription":["254588"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["161857"],"_bbp_forum_id":["27791"],"_bbp_engagement":["81","240","180472"],"_bbp_voice_count":["3"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["190719"],"_bbp_last_active_id":["190719"],"_bbp_last_active_time":["2021-09-15 23:40:21"]},"test":"rameez_ul_haq"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/161857","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\/161857\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=161857"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
