There are two approaches to setup porous medium simulation.&nbsp;<\/p>\n<p><\/p>\n<p>(1) Setup C1 and C2 based on S=C1*mu*v+C2*rho\/2*v^2<\/p>\n<p><\/p>\n<p>(2) Set up C0 and C1 based on S=C0*v^C1<\/p>\n<p><\/p>\n<p>Is the &#8220;Fluid porosity&#8221; box an input only for the C0-C1 approach? Or is it an input for both approaches?&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Do I need to give the right porosity in &#8220;fluid porosity&#8221; box? I did a porous medium simulation with different fluid porosity. I didn&#8217;t notice any effects. There is no &#8220;fluid porosity&#8221; in the formulation of source term S. So i don&#8217;t understand how fluid porosity plays a role in the simulation.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/5853c5e6-3d43-4a8c-b7b2-aa4500f0d4d8\/d942a297-d9b2-4b98-8da6-abe0002925b0_pm.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Please let me know if you need any more information from me.&nbsp;<\/p>\n<p><\/p>\n<p>Thank you.<\/p>\n<p><\/p>\n<p>Alex<\/p>\n","protected":false},"template":"","class_list":["post-45310","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["17491"],"_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"],"_btv_view_count":["3549"],"_bbp_subscription":["240087"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["45310"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","165116"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["118583"],"_bbp_last_active_id":["118583"],"_bbp_last_active_time":["2020-06-22 18:34:28"]},"test":"alexc"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/45310","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\/45310\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=45310"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
