The concept of harmonic thermal conductances

The concept of harmonic thermal conductances is very well suited for modelling dynamic thermal behaviour under periodic boundary conditions. A method for implementing such a model in simulation software is proposed and compared to simplified methods currently employed in international norms and standards. The practicality and efficiency of the harmonic approach is demonstrated using an appropriate simulation software package (“AnTherm”), which allows the three-dimensional, time-dependant visualisation of simulation results. In conclusion, arguments for specific future developments are presented, including the potential for model translation into 4D-enabled virtual environments.

The paper "Practical implementation of a harmonic conductance model
in thermal simulation software" has been presented lately during the 9^th Nordic Symposium on Building Physics held in Tampere (Finland) from 29^th May till 2^nd June 2011.

Version 6 des Wärmebrückenprogramms AnThem wird Anfang September 2010 verfügbar sein

Früher als Erwartet wird die neue Version des Programms AnTherm zur Berechnung von Wärmebrücken am Beginn vom September 2010 freigegeben.


Technologische Migration auf die neue, geprüfte Plattform ermöglich noch einfachere Installation, schnellere Ausführung, kürzere Rechenzeiten, automatisierte Optimierung der Laufzeitkomponenten des Programms auf die technische Gegebenheiten des Rechners und stellt somit die effiziente Nutzung im Vordergrund.

Mit dem Einsatz modernster Visualisierungsplattform in neuester Version sind noch genauere, bedarfsgetriebenen recheneffizienten Visualisierungen möglich – sogar als binokulare stereo 3D Darstellungen.

AnTherm goes parallel

The heat bridges simulation software AnTherm goes next major step further in improving the calculation performance and thus drastically reducing time required to receive primary indicators for complex three dimensional building components.
According to an earlier project announcement the main simulation engine of AnTherm now executes on multiple processors in parallel. The evaluation of boundary condition independent indicators, such as thermal coupling coefficients, utilizes up to all processors or processor cores in parallel. By distributing the calculation to several processors simultaneously calculation results are obtained faster.
Following benchmark proves this major improvement: a calculation of a model with 600.000 equations (thermal steady state heat flow) completes after 14 seconds when run on one processor compared to less then 10 seconds when run on dual core system utilizing both cores. When run on four cores (which is typical to most currently manufactured business personal computers) the results are obtained at less then 5 seconds!
