HTflux is purely two-dimensional as it was optimized for fast and efficient thermal bridge calculation. Although based on the same physics, three dimensional simulations involve a disproportionate effort compared to 2d-simulations. Especially the creation of the model as well as the finite element meshing are time consuming and require a certain level of skill. The time to perform a 3d-simulation is usually increased by a factor of 10 or more, compared to a 2d-simulation having the same number of details. Therefore we recommend that if you do need a three dimensional simulation you should contact us. With our experience combined with the use of modern academic simulation software we are able to perform 3d-thermal simulation efficiently and accurately. We can therefore offer you this service at a very competitive price level.<\/p>\n<p>Just like 2d simulations performed with HTflux, 3d finite element thermal simulations offer you a lot of insights regarding potential optimizations and enable you to calculate design values, such as:<\/p>\n<ul>\n<li>point transmittance value (\u03c7-value, &#8220;chi&#8221;-value)<\/li>\n<li>minimum surface temperatures<\/li>\n<li>distribution of temperature<\/li>\n<li>distribution of heat flux<\/li>\n<\/ul>\n<p>Below find an exemplary 3d simulation of a steel roof anchor mounted on a flat concrete roof,
