Simple Linear Thermomecanical analysis Question.

Humberto · 2014-06-26 23:41:15

I have a mesh (it is a wall system) I imposed different temperatures inside and outside and solved the thermal analysis, now I am trying to impose these temperature field as a loading on my mechanical analysis to show a deformed shape for temperature.

How do I impose the calculate temperatures in the first part of my analysis into my mecanical loadings.

Please help!

Hoi Humberto,

please have a look at the slide 16 and further:

http://www.code-aster.org/V2/UPLOAD/DOC … ermics.pdf

<code>
....
thmodl2=AFFE_MODELE(MAILLAGE=memesh,
AFFE=_F( TOUT='OUI',PHENOMENE='THERMIQUE',MODELISATION='AXIS',),)

...
resproj = PROJ_CHAMP( RESULTAT=thresu,MODELE_1=thmodl, MODELE_2=thmodl2,)

mymat= AFFE_MATERIAU( MAILLAGE=mymesh,AFFE=_F( TOUT='OUI',MATER=steel,),
AFFE_VARC=_F(TOUT='OUI',NOM_VARC='TEMP',EVOL=projres,VALE_REF=20,),

....
mecres= MECA_STATIQUE(MODELE=mymodl,CHAM_MATER=mymat,EXCIT=_F(CHARGE=mecload,),)
</code>

[If I look carefully at the code I think there is a typo in the presentation: projres <--> resproj?]

The presentations are worth a look at:
http://www.code-aster.org/V2/spip.php?article282 (06_Thermics is selected above).

If you still have questions, return to this forum.

Keeswouters: Thank you so much!

the document is very clear I will report If I could get it to work.

Edit: I guess I should have started there, I just got lost reading comm files of test cases and the other documentation.

But I am really excited now that I think I will be able to get it to work!

Overwhelmed by the abundance of data instead of (positive) matter.
