Simulating the complete HAMSTAD benchmark using a single model implemented in Comsol

Benchmarks are important tools to verify computational models. In the research area of building physics, the so-called HAMSTAD (Heat, Air and Moisture STAnDardization) project is a very well known benchmark for the testing of simulation tools. In contrast to earlier work where we used multiple (Comsol) models, in this paper we simulated all five subtasks of the benchmark by using a single model implemented in Multiphysics software Comsol 5.2a. We conclude that the single model provides satisfactory results on all parts of the benchmark and is therefore applicable for a wide range of HAM problems.
