No Static Entropy Generation
 

Hi everybody,
I'm doing a simulation at very low RE number (1e4) and very low velocity. the simulation is also with no heat exchange and incompressible flow, so I'm using the Isothermal model. In the solution there is no entropy rise, as the Static Entropy in the Post is 0 everywhere. However, the viscosity effects in the simulation are well captured, as I obtained a total pressure distribution verified with experiments. So basically everything seems to work, but the entropy is not calculated. Do you think it's a problem?
Thank you a lot,
Giacomo

Consider the definition of entropy : dq=Tds.
Your isothermal condition falls to isentropic.
