This geometry was first created in ntopology as two parts consisting the fluid domain (channel) and wall, later both were exported as a stl mesh into spaceclaim using assembly option as shown in the figure attached. The assembled geometry consisted of two facets, the channel facet (described as fluid) and the outer wall facet (described as solid). When I try to import the spaceclaim file into wrokbench, the geometry is updated well but when the meshing is done then it fails displaying the error message that &#8216;the mesh generation didn&#8217;t complete due to poor quality&#8217;. I came accros a few threads with similar problems and they were advised to look into the dimension and element size. The dimension of my channel is 50*0.5*0.5 mm and outer wall is 50*0.6*0.6 mm (l*b*h), and I tried different element sizes from 10e-3 to 10e-9, but it fails everytime.&nbsp; &nbsp;<\/p>\n<p>Also, since the parts were imported as stl mesh into spaceclaim and later into workbench, defining the named selection for non-uniform channel shape is not happening. Kindly look into this people. Thanks in advance.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/29-01-2024-1706491955-Screenshot (164).png\" alt=\"\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/29-01-2024-1706491903-Screenshot (163).png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-346910","topic","type-topic","status-closed","hentry","topic-tag-Structuredmeshing-2","topic-tag-meshansys_meshingextrude_volume-1","topic-tag-meshingerror-1","topic-tag-ansys-cfd-1","topic-tag-ansys-cfd-post-1","topic-tag-ansys-cfx","topic-tag-assembly-meshing","topic-tag-cfd-microfluidic","topic-tag-microchannel"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["336321","200","338679","346790"],"_bbp_author_ip":["23.206.193.154"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["4081"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["346910"],"_bbp_forum_id":["27822"],"_bbp_engagement":["200","336321"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["347645"],"_bbp_last_active_id":["347645"],"_bbp_last_active_time":["2024-01-31 12:03:19"]},"test":"mohammad-arfinmonash-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/346910","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\/346910\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=346910"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
