I am interested in heat conduction across the interface between two blocks. I have created two block in Rhino and generated volume meshes using Griddle. I have then imported the two adjacent blocks into 3DEC. I am heating the base of one block and I am hoping to be able to have heat conduction occur across the interface between the two blocks. So far when I heat the bottom block heat is not conducted to the upper block even though they are in contact with each other (see attached images). I have two questions:
Is it possible to have heat conduction across the interface of two separate blocks assuming they are sufficiently close to each other?
Do I need to setup some kind of interface between the two blocks and apply thermal properties? I see that subcontacts have been assigned to the interface but I am wondering if I need to apply thermal properties to them and if so how I do that.
