Hi,



I am trying to run Numerical Simulation of Battery Cooling system using OpenFOAM-V11.



There are 3 cases for this simulation. Case 1 was creating the mesh and in Case 2 we will be applying the thermo physical properties. I was able to generate the mesh and I am facing some problem while running case-2.



I am facing this error while running the chtMultiRegionFoam solver


--> FOAM FATAL ERROR:
Negative initial temperature T0: -1.44502

My solver is running for a while and then it throws this error!



I have attached my whole sample here: case2-proper.zip


Would be helpful If someone let me know where I am going wrong! Thanks in advance!

Hello,
I am encountering a similar problem of a negative temperature. Will you please help me.
