Hi,
I'm trying to define the viscosity of a liquid as a temperature dependent polynomial function in Fluent. I plotted the experiment data in Excel to get the trend line and polynomial equation. Pls, see "Excel poly.jpg" to see the experimental data and polynomial function. When I tried to enter the coefficients in Fluent to define viscosity, I got a completely wrong graph. Pls, see "Fluent poly.png" to see the Fluent graph I got for the polynomial function. Can you pls tell me what I have done wrong? Thanks in advance. Best regards, M |

Thanks, Your suggestion helped.
Increasing the significance of the coefficients helped. Thanks again. |
