It is weird that it didn’t work. It does nicely here:

I know the number of the lower surface, and the name of the upper surface, but I have three surfaces that has been created that I can access as Ex1[2:5]. I have tried several possibilities but I do not know how to do what I want: Physical Surface('interface_stationary_1')={Ex1[2:5]}; Best regards. -- Luis Parras Anguita Profesor Contratado Doctor Departamento de Ing.
