Hi,

I've been trying to model a tank system for my degree using transisnet thermal analysis. I believe I have everything set up correctley, but the issue I have is setting the inner tank temperature with insert->temperature, leads to a constant temperature. I've tried editing it but not had any sucess. I am only modelling half the tank as it is symmetrical, and I've included some screenshots of the setup below. Any help would be appreciated!

The time steps are every 60 seconds up to one hour, as you can see the temperature defaults to staying at the -259.2 for the whole hour, when I want to see how much the temperature within the tank will increase over that period.

Are you modelling this in Fluent or Mechanical?

HI Rob,

 

I have tried running it in both steady state thermal and transient thermal. I've never had any teaching on either so have been trying to figure it out as best I can.

 

Thanks

OK, but that's the Mechanical solver, not CFD.

I think I have posted in the wrong section, I am definitely using transient thermal, but am having issues setting up a non-uniform initial temperature

Hi Lydon,

If you have the varying time-temperature data in excel then copy and paste the data from excel in Mechanical Tabular Data for time and temperature.
