Particle temperature setting with heat source routine
 
Hello,

i am using the fortran file heatsource.F to set the temperature of my particle (Inlet) which is flying through a fluid with a certain temperature.
Under Default Domain->Fluid Pair Models->Heat Transfer Option-> Particle User Source i can link the fortran file with my model. In the heat source file you have a equation

SOURCE = FACT*(TEMP_FL-TEMP_PT)

Now replacing TEMP_PT with a value like 500, then you have an equation

SOURCE = FACT*(TEMP_FL-500))

So the Particle temperature in the next time step should be set up to 500 K. But in my simulation the particle temperature dont get 500 K. What could be the reason for that? How would you manipulate the particle temperature in fortran?

Best regards
