Hi guys

I am currently modelling a chemical reactor which has 2 fluid zones. In the first one the reactant will heat up by a heat flux at the wall and in the second one chemical reaction will be happen in a porous zone. I did model the geometry in DM and import it to ICEM via workbench reader. Note that there are 2 interface BC, to be able to define the interface in Fluent.

The problem is that when I merge the two blocks which I created for zones, one of the interfaces will disappear at the final mesh. On the other hand, when two separated blocks was used the mesh quality is awful at the interference. Thank you in advance for your help...
