I will first try 1e-04 for the absolute convergence criteria. If it works, I will go with 1e-03.nActually, I set the Max. Iterations\/Time Step to be 120 as you can see in the screenshot above. Maybe you overlooked that!?nWhat do you mean by the implicit formulation of the time step? How can I define this? CFL is default and set to 2 (see screenshot above).nI use to have one monitor for my contour of phases (that&#8217;s what I mainly want as a video\/animation) and one monitor for the residuals. Since I don&#8217;t have a continuous flow with an output, I can&#8217;t monitor mass imbalances, if it is that you are referring to. Are there other parameters I should monitor to check convergence?nThanks again! Kind regards!nRaffaelnn<\/p>\n","protected":false},"template":"","class_list":["post-141718","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/141718","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\/141718\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=141718"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
