As single machine alone wouldn&#039;t fit memory requirements, I opted to use distributed computing feature. So I setup 3 machines for simulation using <strong>Intel MPI. <\/strong>But the adaptive meshing process got terminated at second pass without stating the detailed reason for simulation error [tried multiple times and did reinstallation couple of times in all machines, error ceased to disappear \ud83d\ude41 ]. Then I reduced the simulation volume to see if issue persists, and it actually does. Somehow I managed to finish the adaptive passes on a high memory machine and thought of giving a shot to see if the error occurs in solving sweep frequencies too. This time it got distributed without any issues and solved all sweep frequencies as expected. I wanted to see if the issue is more related to MPI vendor, as in previous version (2020 R1) was using the platform-computing MPI to perform simulations. Simulation got completed without any errors in 2020 R1 with same Intel MPI distribution. I am baffled why the 2021 R1 is stuck with the adaptive passes, I would appreciate your help if you let me know how to get rid of this. <\/p>\n<p>P.S. : I tried both auto and manual HPC settings and verified all the MPI test commands. Firewalls are completely turned off. \ud83d\ude42<\/p>\n","protected":false},"template":"","class_list":["post-159637","topic","type-topic","status-closed","hentry","topic-tag-adaptive-meshing","topic-tag-distributed-computing","topic-tag-hfss","topic-tag-hpc","topic-tag-intel-mpi-1"],"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":["618"],"_bbp_likes_count":["0"],"_bbp_subscription":["253205"],"_bbpmt_movedon":["2022-07-01 17:10:19"],"_bbpmt_movedfrom":["151970"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159637"],"_bbp_forum_id":["27793"],"_bbp_engagement":["174019","179092"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["182705"],"_bbp_last_active_id":["182705"],"_bbp_last_active_time":["2021-06-23 13:08:54"]},"test":"mahesh2444"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159637","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\/159637\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159637"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
