Hi there,<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
I am trying to mesh a delta wing in ansys mesher. I have created a body of influence around the body and used the following paramaters<\/p>\n
<\/p>\n
General Mesh settings:<\/p>\n
<\/p>\n
Fluent Mesh<\/p>\n
<\/p>\n
Capture Curvature No<\/p>\n
<\/p>\n
Capture Proximity No<\/p>\n
<\/p>\n
Mesh Defeaturing No<\/p>\n
<\/p>\n
Max Angle 180deg<\/p>\n
<\/p>\n
max height over base 0.7<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
body of influence:<\/p>\n
<\/p>\n
element size: 5e-3m<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
face sizing (on the wing):
element size: 1e-3m<\/p>\n
<\/p>\n
capture curvature no<\/p>\n
<\/p>\n
capture proximity no<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Inflation (on the wing):
1st layer height: 1e-6m
Number of layers: 45
growth ratio: 1.17<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
With these parameters I get a mesh without any warnings. However, it results in a rather large mesh. In order to bring the element number down I would like to increase my element size in the body off influence. When changing it to 8e-3 I suddenly get stair stepping. I was wondering why I get stair stepping when changing the body of influence element size and what can I do to avoid stair stepping? Is there a way for me to know how face sizing, inflation layer and body of influence sizing have to relate to each other? <\/p>\n
The trouble is that I need a lot of elements on the wing surface so increasing the face sizing on the wing is not an option. I can increase or decrease the 1st layer height but will need to change the number of layers accordingly. <\/p>\n","protected":false},"template":"","class_list":["post-34002","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["6174"],"_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","0","0","0","0"],"_btv_view_count":["1415"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["34002"],"_bbp_forum_id":["27790"],"_bbp_engagement":["62","159370"],"_bbp_voice_count":["2"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["81114"],"_bbp_last_active_id":["81114"],"_bbp_last_active_time":["2019-03-22 04:53:03"]},"test":"catiav5"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/34002","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\/34002\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=34002"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
