Thermal analysis

Dear Caelinux experts,
I have been using CAElinux only for a week now. Really impressed!! But have gotten stuck now.

Please dont flare me if this is a basic question. I am still learning.

I am trying to model heat transfer through a rectangle made aluminium. The solid block has a small hole in between and I apply heat source along the circular lines in the hole. now I want to see the temperature distribution.

I used Salome to model and anlyse this. In the thermal analysis wizard in Salome, I specify a K value (which I assume is for the material. But dont know how things are going to work out when I have two materials. But will come to it later). I created a group for the inner circle and apply 100 degree centigrade to the inner lines. I created a group for the outer lines of the rectangle. Now I dont want to apply temperature to those lines. Instead I want to apply h (convective coefficient) and want to solve for a steady state analysis.

Q1. Is it at all possible just by using Salome??
Q2. I found a tutorial here
caelinux.com/CMS/index.php?option=com_jo...;id=2574&catid=5
Cant really understand much from the tutorial as dont know how to run it. Should I run it from the terminal or should I run it through Salome? Please let me know how to go about solving it. When I solve in Salome, it spits out some error "error while exporting a reference to a file0:1:1:3"".

Q3. My understanding is Salome alone cannot do it. And I have to use Elmer or Aster. Can you experts point me to the right source?

Thanks in advance for your patience,
Cheers,
Lax

Dear experts,

This, probably, is the lamest question on this forum. I am embarrassed. But hey come on! Everyone is a new comer (but not as dumb as me). Anyway, I have created a tute and thought will post it here or on the wiki (for people to get started). But I want somebody else to see if it is ok before I post it online and feel crappy, once again ;) .

Any takers (or any experienced users [file] )!!

Hoi Lax,

no problem. I will have a glance at it if you are willing to send it to me ...

kind regards - kees

Interest: structural mechanics, solar energy (picture at 'my location' shows too little pv panels)

Thanks Kees Wouters! Thats so kind of you. This is a very very simple tute of the problem I had posted.

Ok now, can you please let me know your email? or you can send me a test mail at This email address is being protected from spambots. You need JavaScript enabled to view it.

I will send you the attachment right away.

thanks matey,

Hey Kees Wouters,
I could not upload the files from work on this forum. So if it is not a problem, here is the download link: www.usaupload.net/d/gblhk2rse3y

thanks mate,

[solved]
I was trying to solve a transient thermal analysis with on/off loading. After much of toiling could finish it.

Probably this is a trivial exercise for all you experts out there, but for a beginner (like me), it was torturous. Luckily I had Kees telling me how to go about doing things in CA. So will upload things on wiki (if anybody is interested)!

@ Kees,
thanks a lot for your advice and more so for the tons of suggestions!
Owe you big time mate!

Thanks,
Lax<br /><br />Post edited by: Lax, at: 2009/09/05 08:09
