Construction set does not converge (1.1)

Hi, another problem here with energy simualtion in 1.1
When I run with default materials then my simulation runs, but when I setup my own then I get the error of the simulation not converging. Any idea what is wrong here? (The idea here is to make just 1 layer cosntructions with minimal requirement for Poland).
