<p data-start=”224″ data-end=”253″>Dear Fluent and TFSI experts,<\/p><p data-start=”255″ data-end=”492″>I am currently working on a <strong data-start=”283″ data-end=”329″>thermal-fluid-structure interaction (TFSI)<\/strong> simulation and would like to clarify several questions regarding the setup process.
