Thermal Topology Optimization

I am trying to work on optimizing a heat sink model based on the attached paper. I am unable to simulate the model by applying CHBDYE as it is not supported in topology. I tried applying heat flux instead but I am having this error - 

Messages for the job:

 
 *** ERROR # 557 ***
 DRESP1 1 is not referenced from within a linear heat transfer SUBCASE.
 This type of response must be specified from within a linear heat transfer 
 SUBCASE.
 This error occurs in DESOBJ 2.


Can someone guide me in the right direction. I did follow this thread -

But havent fig out a way to get the 3D output as Alurcad got.

I attached the 3D model file too.

Thanking You,
