One value is associated with the heat source parameters, which is 0.1, and the other value is related to the mass source parameters, which is 6.0. What is the perfect name for those values? Should I call them that? Is there anyone who can kindly help me understand this? The information will be a tremendous help for me. I have already provided all the details, including the image, equations, code, and parameter values indicated by the red circle.<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/03\/05-03-2026-1772746272-for question.jpg\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-453805","topic","type-topic","status-publish","hentry","topic-tag-AdditiveManufacturingModule-1","topic-tag-cfd-fluent","topic-tag-Directedenergydeposition-1","topic-tag-metal-powder-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["453805"],"_bbp_subscription":["650443","199"],"_bbp_author_ip":["64.251.148.197"],"_bbp_last_reply_id":["453842"],"_bbp_last_active_id":["453842"],"_bbp_last_active_time":["2026-03-06 10:23:08"],"_bbp_reply_count":["3"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["650443","199"],"_btv_view_count":["67"],"_bbp_topic_status":["unanswered"]},"test":"atiqurrahman-ustb17gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/453805","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\/453805\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=453805"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
