The query is regarding the initialization of the temperature field in porous media. I have my model equations in non-dimensional (ND) form (2D).

The dimensionless temperature ranges from 0 to 1. The (hot) fluid is coming to the porous media and the non-dimensional temperature (theta) at the inlet is 1, and the porous medium (LTE model) is at theta=0. I am initializing from the inlet (where theta =1) and patching the porous medium at theta=0. However, I am getting the following message in the console.

"temperature limited to 1.000000e+00 in 60400 cells on zone 2".

And an initial condition theta=0 is not displayed in the contours.

Help will be greatly appreciated.

Hello,
Could you please explain your governing equations ?
Thank you

Thanks for the quick response. I have non-dimensionalized the energy equation for porous media using the local thermal equilibrium approach. So, the Peclet number is the ND number I am having, along with the ND temperature (theta), where theta =(T-T_min)/(T_max.-T_min).
Kindly let me know if another detail is required.
I have altered the material properties and all as per Fluent's governing equation though.

I resolved the issue. The Limits are by default set from 1 K- 5000 K, so the message in the console was popping out. Upon setting the limit to 0 K solves the problem. However, this is not a recommended practice for dimensional equations.
