Dear Gregor, We have a limit for temperatures in case of coupled heat and moisture calculations. Nearly all material properties and functions related to moisture are measured in a temperature range around 20°C. This also means that these material properties become more and more faulty with increasin...

Hello, You have to set a moisture source at the certain position. The climate file for this moisture source must be calculated from the rain flow density normal to the surface. To get this you have two possibilities. 1. create a Delphin project with a wall with the same geometry like your constructi...

Hello, 1. If you have the shortwave radiation normal to your wall you need only one climate data set, SWRadiationImposed. 2. You need to use a detailed interface. This is a set of boundary conditions. You need for each boundary flow one boundary condition. In this you can set all the model data and ...

Hi Gregor, The thermal conductivities of air in the Delphin material database are calculated by using the values from the standard ISO 6946. It includes convection and radiation. I would suggest, as Andreas said, to use our source model for the longwave radiation exchange. The convective part can be...

Hello, You can set a lambda function depending on moisture content. You can find the material file specification here: https://nbn-resolving.org/urn:nbn:de:bsz:14-qucosa-126274 Currently we are working on a manual but its not finished yet. There is a description of the previous version DELPHIN 5. Th...

Dear Jiwon, Which Delphin version do you use? The handling of the convective source is different from D5 to D6. But in general. We calculate the pressure difference according WTA leaflet. That means we take temperatures into account. Only the air flow resistance of the construction is constant. We d...

Hallo, Leider gibt es für das TRY 2017 keine Regendaten und es wird auch in absehbarer Zeit keine geben. Da die Daten berechnet sind, wird das auch schwierig. Im Delphin sind die Daten des TRY 2011 mit Regen angereichert da. Allerdings nicht für den gewünschten Ort. Für Stuttgart gilt hier dir Nr. 1...

Zur Simulation mit Delphin benötigt man häufig Klimadaten. Im Idealfall sind dazu Stundenwerte der folgenden Komponenten erforderlich: Temperatur Relative Luftfeuchte Diffuse Solarstrahlung Direkte Solarstrahlung Langwellige Himmelsgegenstrahlung Reagenstromdichte auf Horizontal Windrichtung Windges...

and try to check out why you have such problems. - exchange some of the materials in order to check for strange material functions - change discretisation - maybe you have special climatic conditions, in this case change also this - try to simulate with different 'maximum method order' in 'performan...

Hallo, So direkt kann ich das jetzt nicht sagen da ich die Berechnungsmethode des ZUB Programmes nicht kenne. Die Methodik selbst ist ja in der Norm nicht vorgeschrieben und es gibt aktuell auch keine Zertifizierung. Da kann es schon sein das verschiedene Programme verschiedene Ergebnisse bringen. W...
