I defined the source term using the Expressions option in Fluent 2020R2. The flow is turbulent and the turbulent model is realisable k-epsilon with enhanced wall function. I have no problem with the momentum source term but when I activate the energy source term the following error will appear:<\/p>\n<p> Fluent Error: chip-exec: function &quot;qi&quot; not found<\/p>\n<p>the energy source term is the momentum source term* x-velocity, as<\/p>\n<p>Velocity.x*fi<\/p>\n<p>I tried different scenarios, such as testing other turbulent models, considering other sorts of energy source terms such as a constant number; however, I got the same error.
