<p data-path-to-node=”6″>Hello,<\/p><p data-path-to-node=”7″>I am planning a 3D tensile shear analysis of a single lap joint (direct bonding of aluminum and resin) using PyMAPDL in Ansys Student 25.2. I have already successfully completed the 2D simulation, but I would like to know if this kind of 3D simulation is fundamentally possible within the free Student license in terms of functionality and accuracy.<\/p><p data-path-to-node=”8″><strong data-path-to-node=”8″ data-index-in-node=”0″>[Analysis Conditions]<\/strong><\/p><ul data-path-to-node=”9″><\/p>\n

  • <p data-path-to-node=”9,0,0″><strong data-path-to-node=”9,0,0″ data-index-in-node=”0″>Dimensions:<\/strong> Aluminum (45x18x1.5mm), PBT (50x10x3mm), Joint area (5x10mm) *Please see the attached image.<\/p><\/li>\n

      \n
    1. <p data-path-to-node=”11,0,0″><strong data-path-to-node=”11,0,0″ data-index-in-node=”0″>Is the mesh count (128k) the only restriction? Is 3D analysis fundamentally supported in the free version?<\/strong><\/p><p data-path-to-node=”11,0,0″>Are there any hidden locks or restrictions on specific analysis algorithms or 3D features in the free student license? As long as the mesh count stays within the 128k node\/element limit, will the simulation run successfully just like the commercial version?<\/p><\/li>\n
    2. <p data-path-to-node=”11,1,0″><strong data-path-to-node=”11,1,0″ data-index-in-node=”0″>If I geometrically model micro-meter (μm) order surface roughness on the joint interface, can the free version solve it accurately?<\/strong><\/p><p data-path-to-node=”11,1,0″>Since there is a huge scale difference between the overall mm-size dimensions and the μm-size roughness, can the solver in the free version fundamentally handle this with high accuracy and precision?<\/p><\/li>\n
    3. <p data-path-to-node=”11,2,0″><strong data-path-to-node=”11,2,0″ data-index-in-node=”0″>Feasibility of using a completely smooth surface<\/strong><\/p><p data-path-to-node=”11,2,0″>If modeling the roughness is too difficult due to the mesh limit, is it realistic and feasible to run the 3D tensile shear analysis by simplifying the joint interface into a completely smooth surface with shared nodes within the Student version’s capabilities?<\/p><\/li>\n<\/ol>\n

      <p data-path-to-node=”12″><strong data-path-to-node=”12″ data-index-in-node=”0″>[Summary \/ Conclusion]<\/strong><\/p><p data-path-to-node=”12″>In short, I would like to know if this simulation is <strong data-path-to-node=”12″ data-index-in-node=”76″>fundamentally impossible<\/strong> with the free license, or if it is <strong data-path-to-node=”12″ data-index-in-node=”136″>fully possible as long as it fits within the mesh limit<\/strong>. If it is possible, are there any specific pitfalls, limitations, or points of caution I should be aware of when using the Student version?<\/p><p data-path-to-node=”13″>I would appreciate any insights on whether the free Student version can handle this simulation.<\/p><p data-path-to-node=”14″>Thank you!<\/p><p data-path-to-node=”14″> <\/p><p data-path-to-node=”14″><\/p><\/p>\n","protected":false},"template":"","class_list":["post-459251","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["459251"],"_bbp_subscription":["619179","240","199"],"_bbp_author_ip":["133.25.249.231"],"_bbp_last_reply_id":["459447"],"_bbp_last_active_id":["459447"],"_bbp_last_active_time":["2026-06-08 04:44:01"],"_bbp_reply_count":["6"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["3"],"_bbp_engagement":["619179","240","199"],"_btv_view_count":["55"],"_bbp_topic_status":["unanswered"]},"test":"masaharu-watanabe-4zstu-hosei-ac-jp"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/459251","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\/459251\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=459251"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
