Constrains equation for heat transfer and electric analysis

[lambert8809]

Dear All,

I want to perform a RVE analysis using ABAQUS to get effective properties. I know how to applied periodic boundary conditions for mechanical problems to get elastic properties of the RVE, but now I want to do heat transfer and electric analysis with the same RVE. I guess I cannot use dof 1-3 in the equations to couple temperature for heat transfer or electric potential, then how can I solve the problems? Any suggestions or comments are great appreciate.


Thanks
Xin
