Miguel,

> My question is what happen if he put on the surface of Zone1 different properties on the same surface of Zone2?
The solver solves zone by zone so when it solves for zone1 whatever boundary conditions are associated with zone1 are used regardless of how it appears to be geometrically. When the solver solves for zone 2 it uses whatever boundary conditions have been set up for zone2. 
The fact that two surfaces have spatial characteristics which are the same or are within some tolerance does not mean they provide boundary conditions to each other unless explicitly set in the topology either by individually choosing "surface in other zone" or by the automatic topology facility.

If you provide a thermal association between two polygons then there are
several checks that are made in the simulator - their surface normals must
be within a certain angular tollerance so that the two polygons are roughly
parallel with each other, the area of each polygon should be about the
same.  It will then look at the constructions and complain if the number
of layers does not match or the layer materials do not match.

Hi all,

I have a doubt about surface attributes.

When we have a 2 zones with 1 surface in common, to this surface in "environment" propreties we have to choice the option "surface in other zone" for the program know this surface is a same the surface in another zone, rigth? My question is what happen if he put on the surface of Zone1 different properties on the same surface of Zone2?


someone can enlighten me?


Best regards,
Thank in advance
