Implementation of dynamic boundary conditions

the use of the dynamic domain expansion can lead to the necessity of setting boundary conditions dynamically. if, for example, a closed room is depicted, the boundary conditions will include an (impermeable) wall. If the dynamic domain expansion is used and the domain starts with a subarea within the room, then the outflow conditions should be set at the corresponding borders and not a wall (the original boundary condition).

The task is to apply the boundary conditions defined in the XML to the boundaries of the physical domain and for the computational domain, the boundary conditions must be set dynamically. That means, if the computational domain is closed with the physical domain, then the boundary condition of the computational domain corresponds to the boundary condition of the physical domain. Otherwise, another condition must be created.
