Hello, 

I am running similar kind of issue, i.e. having triple walls with LTNE model (but my problem statement is different and can mention if needed). Out of three walls, two are coupled walls (belonging to fluid domain), however wall belonging to solid domain has no pair to it. If I run the simulation with via system coupling boundary condition, there is no heat transfer at all from this third wall. 

Not I tried to fuse face zones - it gives me error as "Node 0: Process 58397: Received signal SIGSEGV." 

My additional concern would be: can we fuse three faces using the TUI command? Or is is only two faces? I tried fusing two or three faces, both did not work. 

Just wondering if you were able to resolve the issue?
