HAMSTAD Benchmark 2: Moisture Transport in a homogeneous wall

Application ID: 86381

This case shows how to simulate moisture transport in a homogeneous wall under isothermal conditions. With this assumption, an analytical solution can be calculated. The homogeneous layer is initialized in moisture balance. At the beginning of the simulation, the relative humidity of exterior and interior is shifted to lower values. The 1D model is the second benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical simulations for coupled heat and moisture transport in building materials.

This model example illustrates applications of this type that would nominally be built using the following products:
