Hi KR,<\/p>\n

It is difficult to gauge the exact reason based on the description provided. There could be multiple reasons why the simulation would diverge, such as mesh, case setup, time step size, etc.<\/p>\n

Here are the general guidelines that you could check to ensure they are incorporated in your simulation:<\/p>\n

    \n
  1. Solver schemes<\/strong> \u2013 Use Implicit.<\/li>\n
  2. Time step size<\/strong> \u2013 Use a time step size lower than the one you are currently using in your simulation.<\/li>\n
  3. Primary phase<\/strong> \u2013 If it is a closed domain, the primary phase must be a compressible fluid (I assume it would be air in your simulation).<\/li>\n
  4. Ideal gas<\/strong> \u2013 If it is a closed domain, enable ideal gas for air.<\/li>\n<\/ol>\n","protected":false},"template":"","class_list":["post-365753","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/365753","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":3,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/365753\/revisions"}],"predecessor-version":[{"id":377916,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/365753\/revisions\/377916"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=365753"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
