Hello, I am working on validation of thermal radiation and I am using steady state thermal analysis in workbench.

I wanted to apply radiation to an enclosure along with convection inside it, I used commands to remove bulk temperature constraint as follows:

/gopr                                 

/prep7                                

nsel,none                          

N                                         

 

FLUID_TEMP=ndnext(0) 

cmsel,s,For_Convection 

esln                                      

esel,r,ename,,152             

*get,AR80,elem,elnext(0),attr,type

keyopt,AR80,4,1               

keyopt,AR80,5,1               

emodif,all,-5,FLUID_TEMP

/solu

allsel,all

cmsel,all

But it is showing error as enclosure type PERFECT was incorrectly chosen. (I have selected all the surfaces for surface to surface radiation).

 

I would be happy for the help

I have used the same commands previously and it worked. The only difference is slight change in the geometry

Hello Sahithi,

Thanks for sharing the solution with the community. I'm sure it will help other's who are facing similar challenges.

Best,
