However, I didn&#8217;t get the answer to my question after going through the suggested chapter. The only thing related to the question I found was that the boundary condition Im asking about is the default at the walls. Let me rephrase my question. Some problems at the inlet don&#8217;t provide a specific species mass fraction (also called Dirichlet boundary condition) but they provide a specific mass flux (or Neumann boundary conditions). In this case, how can I add this mass flux in fluent since at the species option under velocity inlet there is only an option to add species mass fraction only?<\/p>\n","protected":false},"template":"","class_list":["post-290892","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Thank you for your reply.
