Autodesk Simulation Results: Ascending/Decending Order

[Anonymous]

I have created an FEA simulation but can not figure out this problem. When I run the analysis my results are generated and when I tell the animation to run the program maps the thermal properties moving across the surface. My issue is that the program runs the results starting at the highest temperature first and moves towards the initial temperature. I would like to see the results moving in ascending order, initial temperature to the maximum temperature I defined. Is there a way to do this?

I have a few questions about your situation.

1. What type of analysis have you performed? (I'm guessing transient heat transfer analysis but want to be certain.)
2. If the temperature range in the legend has not been set to a constant value, the color pattern on the model can sometimes be confusing. I suggest that you try setting the "Results Contours > Settings > Legend Properties > Range Settings" and enter a temperature range. Does this improve the animation?
3. If this is a transient analysis, does the time (or step number) increase in the correct fashion?
4. Is the problem just with the animation? In other words, if you step through the results manually ("Results Contours > Load Case Options > Next"), are the results changing as you expect?

Finally, there are two types of animations. The software can animate the results within the Results window, or you can create a animation file ("Results Contours > Captures > Animate > Save as AVI") and playback the animation file. Is the problem the same in both situations? If the animation file shows the problem, please attach it to your reply.

Thank you for the help, I should have stated it is a transient heat transfer. Error might be the wrong word for me to use. The results are being displayed as expected but as I step through (I have 72 steps) step 1 shows the object at hottest point in  the transfer and as I step through towards 72 the temperature decreases. What I would like to happen is for step 1 to show the initial temperature I set for the model and as I step through show how the thermal analysis changes as the temperature increases. 

I hope this is making sense, I am new to Simulation Mechanical and heat transfer.

Thanks for the help.

Hi Jacob,

I suspect that you have a problem with the applied, initial temperature, or the default temperature. Note that the load curve factor has different meanings depending on the type of load. For some loads, the factor is a multiplier to the user input, and for other loads, the factor is added to the user input.

If you cannot find the problem, perhaps you can provide an archive of your model. See the discussion "Create, Post, or Provide an Archive of your model". Please indicate which version you are using since older versions of the software cannot open models created with newer versions.

It was a simple mistake regarding my load curves. Thank you for your support.
