QuickField simulation example

QuickField validation of the test case A.1 presented in ISO 10211:2007 Thermal bridges in building construction.

Problem Type
Plane-parallel problem of heat transfer.

Geometry
Thermal bridges in building construction QuickField validation of the test case A.1 presented in ISO 10211:2007 Thermal bridges in building construction Media No heat flux T = +20°C 0°C 0°C h w

Width w = 4 m, height h = 8 m.

Given
Thermal conductivity of the media λ = 1 W/K-m.

Task
Determine the temperature distribution in the media in reference points of the rectangular grid 1x1 m.

Results
Temperature distribution in the media:
EN ISO 10211:2007 test case 1 temperature

Temperature calculated in QuickField is presented in the table below (reference temperatures are shown in the brackets). To comply with the ISO 10211:2007 the difference between calculated and reference temperatures should be less than 0.1°K. This simulation accuracy complies with the requirements of ISO 10211:2007.
