The modern computer-aided simulation is a fast and cost-efficient method for product development as well as a supplement to or substitute for physical testing. We offer simulation-based analyses around the material wood, e.g. for questions regarding heat and moisture transport, indoor climate predictions or component deformations. Our broad, networked knowledge and modern infrastructure make us the ideal partner for simulation-based research, product development and material characterisation. HFA Simulation Center is the central point of contact for this.


Simulation-based research

Simulation methods, e.g. finite element methods (FEM), are a versatile addition to our possibilities in the field of research and development. Simulations can complement time-consuming or cost-intensive measurements or even replace them completely in some areas of application.

Product development

In traditional product development, cycles from design via manufacturing all the way to physical testing must be repeated over and over again. Simulation tests on digital twins of the product allow this process to be implemented much faster and more efficiently.

Material characterisation

The infrastructure for material characterisation available at HFA forms the basis for the development and validation of meaningful and practical simulation models.

Unsere Leistungen

Deformation analysis of components

We simulate the load-, temperature- and/or moisture-induced deformations of components, such as CLT ceilings or parquet floorboards. By studying various usage scenarios, we support companies e.g. in their product development.

Analyse der Schnittholzproduktion

Wir führen Simulationsanalysen zu Ausbeute und Qualität des derzeitigen oder eines angestrebten Produktionsprozesses durch. Einbezogen werden Rundholzqualität, Einschnittwahl, Zielprodukte, Scanningtechnologie und Sortierzeitpunkte.


Wir führen komplexe Raumklimasimulationen und Energiebedarfsprognosen unter Berücksichtigung diverser Einflussfaktoren (z. B. Standort, Verschattung, architektonische Gestaltung, Glasaufbau, Luftwechsel, interne Lasten, etc.) durch. Außerdem erarbeiten wir Nachweise des sommerlichen Wärmeschutzes gemäß ÖNORM B 8110-3.

Big Data Handling

We use state-of-the-art statistical techniques and analytical methods to interpret the large amounts of data often generated in simulations and to create meaningful visualisations.


Simulation of heat and moisture transport

We simulate the heat and moisture transport through components under different boundary conditions (e.g. different locations, orientations or room climates) according to ÖNORM EN 15026 and WTA-MB 6.8. These analyses can serve to assess the durability of components and materials. We also use our simulation tools to develop hygrothermal verifications in accordance with ÖNORM B 8110-2.

Material characterisation

We determine various physical and chemical material properties as input data for the simulation (e.g. strength and stiffness values, water vapour diffusion resistances).
