Assign different heat transfer coefficient

Recommended Posts

Hello everyone

 

As there is convection, I use MAT4, which also contains the heat transfer coefficient H. Now I am woundering, how can you specify two different heat transfer coefficient on certain surfaces of the model? 

The heat transfer coefficient is actuallly not a material property, so I am woundering if this is the right way to go. How can two different heat transfer coefficient be assigned?

 

Thank you in advance for your help!

Thank you Rahul! 

 

Does this interface come from the group 'CONVECTION'? Because the default there is FTYPE 0, with which I can assign MID, but no H1. If I change FTYPE to 3 I can assign a H1, but no MID. 

 

Do you know why I can't assign both?

Okay I can assign MID and H1. But there is still a problem. The temperatures are not including any convection. 

Can I still use MAT4 and specify there the thermal conductivity (K) and leave the heat transfer coefficient (H) empty?
