Ensure that you have a geometry file which has multiple faces along the path you want want to simulate the moving heat source
This can be achieved by using “Imprint Face” option in Design Modeler while Extruding lines
Do remember more the number of patches you have the more better the moving heat source
Then import the Geometry into
Analysis Systems → Transient Thermal
Enter the Setup Module in Transient Thermal,
Double Click (DC) on Setup and the Simulation window will open.
Note that we are using default material properties of Structural Steel, if you have specific properties you will have to enter the same in Engineering Data
In the Tree Outline (TO) of Transient Thermal, Right Click (RC) on Transient Thermal and Insert “Heat Flow”
Apply heat flow to all the patches created separately ( we are using an arbitrary value of 50 W ).
As seen above, there should be Heat Flow items in the TO equal to the number of Patches.
Now Left Click (LC) on Analysis settings and below the details of Analysis Settings
In the Details of Analysis Settings
Number of Steps = No of Patches
Since our model has 5 patches, we have 5 Heat Flow’s in TO, and Number of Steps have been kept as 5
In the TO, now LC on Heat Flow for the First Patch.
Since No of Steps are 5, the load will now be seen in Tabular Format
Now the logic of moving heat flow is that, if heat is moving, it will move from one Patch to another. So if Heat moves from Patch no 1 to Patch no 2, it should not be active on the previous patch.
So heat for Patch no 1 should be active only for 1st Step, and should be de-
Now, in tabular data, select the Steps which we want to Deactivate (use Cntrl) and then Right Click (RC) and choose the option deactivate at this Step
The Deactivated Steps will appear Gray, while active ones will be white.
Do Remember to Deactivate the previous step for a Patch
Patch No 1
Deactivated from Step 2 onwards
Patch No 2
Deactivated at Step 1
Active for Step 2
And deactivated onwards
Patch No 3
Do apply some arbitrary temperature value at some surfaces otherwise solution will be indeterminate
Once done proceed to solve the Transient Analysis
