Transient temperature flow through material

Recommended Posts

Hello,

 

I am having difficultly to construct a model that shows temperature flow through a material. Attached is my model. I have one surface (bottom) at 100 degrees and initial condition of 25 degrees. It produces an output but it's not correct. Any ideas?

Hello @Prakash Pagadala

 

I've looked at the tutorial for guidance and that's got me to where I am now. That example is a lot more complicated than mine which may be why I'm getting stuck.

 

Any other guidance?

 

Cheers,

Tom

Hi @Prakash Pagadala

 

Attached is my latest attempted, following OS-T: 1090 example

 

I expect that at t=0 the temp of system will be 25°, as time increases the boundary where temperature is at 100° will slowly heat up transferring through the component, from x=0 to x=10.

I can see what you have done and where I was going wrong thank you.

 

However, the model still won't run - see error message below.

 

 

 

 There were 400 error messages during input processing.
  The first message is repeated below:


  *** See next message about line 484 from file:
      W:/Stress Analysis/T Mansell/Practice 7.hm
   "CQUAD4         1       0     126     131     122     123"

  *** ERROR # 1000 *** in the input data:
  Incorrect data in field # 3.

Hi,

 

Looks like while exporting Property is missed out, sorry about that. 

 

Can you check the component whether property is assigned or not,

 

If not, please assign the property and run again.

Thank you for your help, I will try develop this model further.

 

However, the model initial start temperature is 0, although set to 25?

 

When you load the model up it is correct on frame one/t=0, but as soon as its cycled through time it adjusts to 0° at frame 2

 

Cheers,

Tom

We checked with experts and it seems the heat capacity on material is missing. We can add a warning in this case. 

Also, pay attention to the following warning in the out file.

*** WARNING # 5062

Non-zero SPC will be considered as zero SPC for transient thermal

 analysis, except when used to specify ambient point for convection.
