problem with level set and heat transfer in fluids when used together

Please login with a confirmed email address before reporting spam

I have simulated the merging of two glycerol drops with one drop on a surface and the other one just touching it from the top. At first i used the laminar two phase flow level set physics just to animate the merging as a function of time, which completed the task well, but now i want to find the associated temperature field for this simulation and i intend to find the heat transfer across the surface over which these drops are merging.so for this purpose i added the heat transfer in fluids node to my model and applied initial values in terms of temperature to the fluid domains and for the initial velocity field i used tpf/fp1 and then i clicked compute. there was no error and the computation finished but then when i scrolled down to the results i do not find the temperature plot, instead the computation returned the velocity field exactly similar to what i had obtained while using the level set node alone. what i mean to say is that the model behaved as if it didn't have any input from the heat transfer node. i think there is a coupling issue here. will be highly grateful if someone could tip me on whats missing in my model :)
