Hello, <\/p>\n
<\/p>\n
I am wondering if there is a “best approach” to “re-using” simulation settings between altered simulation runs.<\/p>\n
<\/p>\n
In a very general example, say I run a given simulation that uses an inlet velocity of 0.01 m\/s (along with other required parameters). <\/p>\n
<\/p>\n
After this simulation and resulting post-processing are complete, I would like to run the same simulation but now with an inlet velocity of 0.02 m\/s. (SKIP TO “MAIN QUESTION” below for the gist of this post)<\/strong><\/p>\n <\/p>\n SPECIFIC BACKGROUND:<\/strong><\/p>\n <\/p>\n I have been running into errors (unfortunately, I do not have the correct error codes. From my memory, the error is something like mpt: 99999) upon initialization when I try to perform simulations like in the above example.<\/p>\n <\/p>\n These errors force close Fluent and the only way I have found to consistently prevent them is by resetting the “Setup”, “Solution”, and “Results” workflow tabs in Workbench before fully reapplying my settings again from scratch in “Setup”. As you can infer, for wanting to just change the inlet velocity, this process is extremely cumbersome and time consuming. <\/p>\n <\/p>\n Recently, I have been relying on Journals to try and fast track this process but I have found their reliance on GUI commands to make them somewhat unreliable. I have also tried saving my settings through the TUI command line but I run into issues with this approach because I rename boundaries within my simulation and I think that prevents my settings from fully being applied (i.e. only generic boundary name are present at the start up setup, so perhaps the use of custom boundary names “confuses” Fluent when reading these saved settings files?) <\/p>\n <\/p>\n (I use the LTNE porous media model which represents the porous media by creating a solid domain coincident to a fluid domain, thus producing new boundaries. I then rename boundaries to distinguish between those that are fluid and solid adjacent) <\/p>\n <\/p>\n MAIN QUESTION:<\/strong><\/p>\n <\/p>\n All this is to say that I am looking for a simple, reliable, and consistent why to reuse simulation settings without getting initialization errors. I feel that there must be an approach method that I am missing as I am sure changing things like inlet conditions from simulations to simulation is something that readily happens in both research and industry. <\/p>\n <\/p>\n Any enlightenment on this topic would be appreciated!<\/p>\n <\/p>\n Thanks, <\/p>\n <\/p>\n Ryan<\/p>\n","protected":false},"template":"","class_list":["post-44823","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["17004"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["4027"],"_bbp_subscription":["250390"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["44823"],"_bbp_forum_id":["27792"],"_bbp_engagement":["59","199","176224"],"_bbp_voice_count":["3"],"_bbp_reply_count":["11"],"_bbp_last_reply_id":["117506"],"_bbp_last_active_id":["117506"],"_bbp_last_active_time":["2020-06-12 10:50:52"]},"test":"rymor"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/44823","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\/44823\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=44823"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
