Hi all,


 


My name is Dylan and I can't quite get the software to optimize my model exactly how I have it pictured in my head. I'm fairly new to this type of software as well as optimization itself, so I'm not surprised I got stuck in the first place! I currently am modeling steady state heat transfer through a 2-D radial pipe (much like a cd when you look at it in the X-Y plane). I constrained a temperature (of 3000 K) on the nodes along the inner radius of the pipe and I made a conduction interface on the elements along the outer radius of the pipe (to let the heat out) as well as a heat flux (of -345). When I run the OS analysis option, I get a nice spread for the grid temperature leading to a final temperature (of ~2800 K) on the nodes along the outer radius. So far, I think I am okay up to this point (as some of the numerical analysis I did on a previous flat plate model confirmed that this setup should would). Where I am running into problems is when I try to optimize this model in its current state. I've broken my optimization "wants" into a list.


 


1)     2 responses, one Vol Frac and one Temperature.


 


2)     1 constraint, a Vol Frac of 20%.


 


3)     1 object reference being the temperature on the nodes along the outer radius of the pipe.


 


3)     1 objective of minimizing the maximum temperature on the nodes along the outer radius of the pipe.


 


AND I'm actually unsure whether I need to use the topology panel to utilize the optimizations available to me any further.


 


If anyone has had any experience trying to optimize for temperature or any heat transfer optimization advice in general to offer, please do!


 


I'll continue working minor changes to see if I can get the optimization to actually run in the coming weeks...


 


     -Please let me know if there is any other information I can give about my model that might make it easier to see why I'm running into problems!


 


Thanks for taking a few minutes to read!

Hello Dylan,

 

I am a student seeking answer from you...

How to apply temperature load say 1000k in a component and get thermal stress value....say i want to perform steady state heat transfer to temperature loading.

 

 

Thank You

Ramesh
