Hi Torsten,

Thanks for your suggestion. I actually have two domains separated by an interface. I solve for temperature in the first domain and use the interface values as boundary conditions to solve for temperature in the second domain. Hence I will have multiple nodes at which the temperature must be specified and need to automate the process. Further the temperature at each node is not the same on the interface.

I agree with your idea of creating circular holes. That should work out. For this case I was wondering if there could be any other way of specifying the temperature? Thank you for your time.
