The Solve Adjacency component is working in a diferent way since version 1.1.22.
When we had two rooms with a little displacement between them the way that the component worked was considering the surfaces in contact. This was the same way that legacy component was working.
But with the upgrade to 1.1.23, the solve adjacency component considers that there is no contact between the two rooms
Only if the two rooms are aligned the component solves the adjacency and creates the thermal contact.
Knowing that the two rooms with a little displacement are not correctly modelled (I should split the surface), the way that the previous version and the legacy component worked I think was better.
When we worked with models from other sources with little displacement the new behaviour of the component force us to seek the displacement.
Thank you for your help
