Hello,<\/p>\n

I want to create an ICFD mesh with control over the general element size, and the number of elements on certain boundaries. This, however, is (as far as I know) not possible when meshing with 2DMesh in LS-PrePost. Therefore, I wanted to create the mesh using the meshing tool from ANSYS Workbench, and extract this mesh to LS-DYNA in order to convert it to a multiple solver mesh. When I do this, though, only one FEM part remains in LS-DYNA, and this is the entire geometry. In order to use the ICFD solver, I need all boundaries to be FEM parts (e.g. inlet, outlet, wall, symmetry, etc.). <\/p>\n

So two questions:<\/p>\n

    \n
  1. How do I get more control over the mesh while using 2Dmesh in LS-Prepost (so the ANSYS fluent mesh and LS-DYNA mesh resemble each other to the maximum amount possible)?<\/li>\n
  2. How do I convert an ANSYS Workbench mesh to a working LS-DYNA ICFD mesh?<\/li>\n<\/ol>\n

    Kind regards,<\/p>\n","protected":false},"template":"","class_list":["post-159132","topic","type-topic","status-closed","hentry","topic-tag-2d","topic-tag-ansys-workbench","topic-tag-fluid-dynamics","topic-tag-ls-dyna","topic-tag-mesh-generation"],"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":["1097"],"_bbp_likes_count":["0"],"_bbp_subscription":["122799"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159132"],"_bbp_forum_id":["27792"],"_bbp_engagement":["178074","183162"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["180844"],"_bbp_last_active_id":["180844"],"_bbp_last_active_time":["2021-06-23 23:15:25"]},"test":"lcp"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159132","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\/159132\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159132"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
