  Hello, everyone.
  I'm working on the 12 cells serpentine cooling channel battery pack simulation. In the simulation the fluid(liquid-water)'s temperature doesn't change. In the area-weighted average temeprature graph, it keeps same as inlet temperature. And also in the temperature contour it keep same temperature. How can I fixt it.
  I setted up the conditions as below.
  [Cell Zone Conditions]
  Each battery cells are considered as heat source.
  - Heat generation rate 42400 W/m^3
  [Boundary Conditions]
  - velocity 0.3 m/s
  - temperature 298.15K
  Convection
  - Heat transfer coefficient 10 W/m^2*K
  - Free stream temperature 300K
  - Heat generation rate 42400 W/m^3
  - Temperature 298.15K
  I attached a image of the model and results.
  Thank you!

  Dear,
  It is a humble request. Can you please let me know how the IVC mixture in tutorial 2 (Dual fuel combustion modelling using a 60% sector mesh) of Forte was calculated? I followed the reference paper and used the given values in the IVC calculator:
  
  mass of gasoline = 104.96mg
  mass of diesel = 23.04mg
  Phi = 0.77
  EGR = 0.455
  However, I did not get the same values which are provided in the dual fuel tutorial. Can you please let me know how we can use the IVC calculator to find the mass fractions of species in a homogenous mixture of gases at IVC when gaseous fuel is premixed with the air and liquid fuel is injected directly into the cylinder?
  
  Many thanks!
