Dear all,<\/p>\n

I want to calculate the transient temperature of watering cooling solid with internal heat source. Therefore, I try to use transient two-way coupling calculation to solve the problem (please see pic.1).<\/p>\n

To do this, the external data module is used to import the thermal generation into the transient thermal analysis module and set the analysis time with end time as 10s, the time step as 1s, the time integration as on, and the analysis time in the imported heat generation as 10s (please see pic.2). The transient two-way fluid-heat coupling calculation was performed combined with the iteration of results of the transient fluent calculation (fixed time step 1s, 10 steps in total) and the iteration of the results of the transient thermal analysis module. In the system coupling module, set end time as 10s and step size as 1s.<\/p>\n

My question is why the resulting temperature in the transient thermal analysis module does not change with time after the coupling calculation, but is a constant value that does not change with time (please see pic.3). Do I miss some settings, thank you very much.  I have posted the settings in the following pictures:<\/p>\n
