Warning: the residual minimization scheme stalls, therefore the scheme is initialized and the adjoint advancement is terminated.<\/strong><\/p>\n

** Suggestion: increase the number of modes in the residual minimization scheme if there is enough memory.<\/p>\n

Good afternoon, I'm solving a topological optimization problem. When solving, a warning is issued and further solution does not go. What does this mean? I have been working in Fluent Fluent for 1 year and there has never been such a problem. Mesh triangular<\/p>\n

<\/p>\n<\/p>\n

after that the solution stops<\/p>\n","protected":false},"template":"","class_list":["post-163559","topic","type-topic","status-closed","hentry","topic-tag-Suggestion-1","topic-tag-topology-optimization-fluent-1","topic-tag-warning"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
