There are two issues here, I do not have the license for the seamweld in ncode (as far as I know it is a separate license). The other issue is I am not modelling the weld itself, so as per the guidelines for&nbsp; fatigue analysis for offshore structures, in order to have accurate results at the joints, I need to account for the hot spot stress by extrapolating the stresses around the joint. As I understand, in the fatigue analysis, I need a scalar value at each node to compute the life of the structure (combination method). Again as per the DNV rp c203 guideline, the principal stress is an acceptable measure.&nbsp;&lt;\/p&gt;&lt;p&gt;So if we imagine there is a way to compute the hotspot stress at the desired locations in mechanical; then I would like to modify the stress tensor with the new values at these locations to be able to compute the updated principal stresses which takes into account the notch effect. I am not sure if this makes sense.&lt;\/p&gt;&lt;p&gt;Please let me know what you think.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Many thanks,&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-397791","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/397791","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\/397791\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=397791"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
