Transient heat transfer time step data input or data import

      Pulsed laser heat transfer Simulation : Heat flux occurs only for a brief period (if represented graphically, it may appear as a square wave)

      Could ANSYS provide alternative methods for faster input of time step & heat flux corresponding data?

      Currently, I am aware of how to manually input data but I'm seeking more efficient methods (as my continuous laser heat transfer simulation may involve over 200 sets of transient heat transfer data, manual input is too cumbersome and tedious)

      Hi,

      You can copy and paste all the data from excel into Mechanical.

        Mainly, I need to ensure that Workbench presents temperature data more smoothly during the heating and cooling processes (without the appearance of jagged lines). So, I've opted for this method.

        If I directly import a file to complete the data input for HEATFLUX & TIME STEP, will this issue of imperfect curve plotting arise?

      In addition, you can paste the whole waveform into a single step, you don't need a step for each transition.

        I have been exploring using many steps, which might have been a bit tedious and clumsy. LOL

        and I just attempted to use the method you mentioned, but the outcome wasn't satisfactory (result didnt show any temperature increase).

        Could you please explain the method you mentioned earlier in detail?

        Thank you alot.

      Can you please share snapshot of the data that you want to apply/ import? This will help to comment more.

      Also, the time frame seems too small for any noticeable change in temperature

        hi sir:

        My case involves a Pulsed laser, so massive heat flux occurs only for a brief period (15 picoseconds)

        here is one of my case recipe.

        and I already finished get some data I need, 

        However, the process is very intricate (for example, setting each step’s end of time & timestep, etc. to make the temperature curve more perfect)

        You mentioned above and suggested that I might be able to use Excel to replace my method of inputting options one by one. I am very interested in this and would like to learn from you.

        Below is a picture of how I set the timestep, with the red boxes indicating each place I need to set.

         

        thx again
