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!
