Forte is showing that at 7500 RPM w\/ Spark Ignition at 688 degrees has the peak pressure point below 6000 RPM whereas the GT-Suite is showing it would be below 3000 RPM. The geometry and thermal inputs are the same. Valve timing is the same. Fuel compositions is the same. I am currently experimenting with intake and exhaust valve discharge coefficients. This is different between 3D and 1D simulations when it comes to set up.&nbsp;<\/p>\n<p>1) Can you confirm that Forte will give me realistic results if I modify the RPM and Ignition Timing in tutorial 5? Has this been done by Ansys team to validate the accuracy of the model?&nbsp;<br \/>2) How can I obtain or maybe you can provide Intake and Exhaust Valve Discharge Coefficients? <br \/>3) Is Mass Flow vs Valve Lift for Intake and Exhaust for tutorial 5 available?<\/p>\n<p>Please help. I&#8217;m under pressure to decide what my next move should be.&nbsp;<\/p>\n<p>Thank you so much.&nbsp;<\/p>\n<p>Kind Regards,<br \/>Arturas Gulevskis<\/span><\/p>\n","protected":false},"template":"","class_list":["post-371070","topic","type-topic","status-closed","hentry","topic-tag-ansys-forte","topic-tag-forte-1","topic-tag-forte-tutorial-2","topic-tag-ic-engine-forte-1","topic-tag-ic-engine-forte-2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["33262","14415"],"_bbp_author_ip":["2a01:4b00:a89d:3600:a800:ea06:f853:a2af"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["488"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["371070"],"_bbp_forum_id":["27792"],"_bbp_engagement":["14415","33262"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["377449"],"_bbp_last_active_id":["377449"],"_bbp_last_active_time":["2024-08-06 15:19:31"]},"test":"k1124473kingston-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/371070","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\/371070\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=371070"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
