If you try a much larger value, for example, 1.5, you&#8217;ll see that some of the triangles on the symmetry plane start to become inverted because of excessive stretching. If a much larger bore is needed, you can first scale the whole geometry along desired direction(s) first and then scale the &#8220;liner&#8221; and &#8220;piston&#8221; surface.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ansys.file.force.com\/servlet\/rtaImage?eid=ka0Pf0000000JXJ&amp;feoid=00N3g000000rtaC&amp;refid=0EMPf000000eX6v\" width=\"550\" height=\"324\" \/>&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ansys.file.force.com\/servlet\/rtaImage?eid=ka0Pf0000000JXJ&amp;feoid=00N3g000000rtaC&amp;refid=0EMPf000000eX6w\" width=\"615\" height=\"229\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-318776","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/318776","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/318776\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=318776"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
