6.1.0 - 2020-07-31

This is a major DELPHIN 6 release and as such requires NEW ACTIVATION data. Hence,
we recommend that you install the software first aside the old version in a different
installation directory. For users with active license contracts, simply install the
software, and request a new activation. We will send you the activation info, shortly.

Major feature additions:

* Material Editor - material files can now be edited in the built-in editor. Parameters for
the different model/functions types and be entered, previewed and the
material file can be checked for compliance with the solver requirements.

* Climate Data Preview and Import - Importing (third party) climate data is now fairly easy.
Also, the location view shows a preview of imported climate. In addition
to natively supported formats c6b, wac and epw, the climate editing
tool CCMEditor is available for data conversion/import from various
sources (see

* Construction Editing Improvements - quite a few small changes make editing constructions
easier (see details below)

* New Models - several new models are implemented (see details below)

* Simulation Coupling - DELPHIN now supports the FMI coupling standard, which extends the
use cases/application areas for DELPHIN to actively controled/conditioned
components, including heat collectors (fully coupled to building HVAC systems)
and active components (controlled capillary heatings/pipes). The FMI-export
interface is very generic and allows for very creative co-simulation use.
We recommend use of the free MASTERSIM tool for co-simulation (see

* POSTPROC Features and Bindings - Interaction with POSTPROC has been improved, in addition to
the many new features of POSTPROC itself (see recent POSTPROC releases)

* Improved Command Line Tools - The command line tools CmdDiscretize and DSixOutputConverter have
been reviewed, fixed and most importantly documented (the tools are in the DELPHIN 6
install/binary directory). They are very useful for scripted use of DELPHIN, see:


* Remote Solver Server Integration - The DELPHIN user interface now has much better support for
the remote solver server access. Now user-specific jobs are shown with more robust
control over job runs. This feature is mainly useful for larger simulations running
on dedicated workstations/servers. RSS and documentation are downloadable on

6.0.18 - 2018-09-20
This release of DELPHIN has two very important changes:

* the local data base directory has moved, on Windows from AppData/Local
to AppData/Roaming and on Linux/Mac to ~/.local/share/Delphin6
If you had own database stored here, you need to copy them manually over to
AppData/Roaming. This is not done automatically, to avoid data loss when
using old/new DELPHIN versions at the same time.
* thermal-only calculations made with initial moisture now consider the
effect of the moisture on thermal conductivity and on thermal
storage capacity; the latter being important for soil/ground calculations

the user interface:

- #662 Fixed: Summary file is written also after restarting the simulation

Verfügbare Sprachen

DELPHIN 6 liegt in deutscher, englischer, französischer und italienischer Sprache vor. DELPHIN 5 ist nur in englisch erhältlich.
Für die Programme COND, THERAKLES und den Postprocessor gibt es eine deutsche und eine englische Version.

Für alle Programme, mit Ausnahme von DELPHIN 5, sind zukünftig weitere Sprachen zu erwarten.

Unterstützte Betriebssysteme

Die Windows-Versionen sind getestet auf Windows 7, 8, 8.1 und 10. Für die meisten Programme gibt es jeweils 32-Bit und 64-Bit Versionen, wobei wir die 64-Bit Version auf 64-Bit Betriebssystemen empfehlen.
Für den Fall, dass Windows XP Versionen benötigt werden, senden Sie uns bitte eine Support-Anfrage. Offiziell wird Windows XP jedoch nicht mehr unterstützt.

Mac Versionen laufen, sofern nicht anders angegeben, unter Mac OS X 10.11 (El Capitan) oder neueren Versionen. Um unsere Software auf dem Mac unter neueren Versionen auszuführen, muss man entweder die Sicherheitseinstellungen anpassen, sodass Software auch aus anderen Quellen als dem Apple-Store ausgeführt werden kann. Alternativ kann man auch auf die Anwendungsdatei im Finder Rechts-klicken und Öffnen auswählen. Im daraufhin angezeigten Dialog kann man nun das Öffnen der Software bestätigen, sodass in Zukunft nicht mehr nachgefragt wird.

Linux Versionen werden ohne die in den üblichen Distributionspaketen vorhandenen Laufzeitbibliotheken verteilt. Daher müssen die passenden Bibliothekspakete, vornehmlich die Qt 5 Bibliothek, installiert sein. Die Linux-Versionen wurden unter Ubuntu 18.04 (LTS) erstellt und sollten daher auf vergleichbar alten Distributionen und neueren Linux-Ausgaben lauffähig sein (es werden die Qt 5.9 Bibliotheken erwartet).

Die 7-Zip Archive lassen sich durch folgende Befehlszeile entpacken:

p7zip -d <archive>


Kommerzielle Softwareversionen müssen nach der Installation aktiviert werden. Nähere Informationen zu verfügbaren Lizenzvarianten und Lizenzbedingungen entnehmen Sie bitte den entsprechenden Software-Bestell-Seiten. Bitte senden Sie eine E-Mail an, falls Sie ein formelles Angebot erhalten möchten.

Alte Softwareversionen

Auf Nachfrage können Sie auch ältere Softwareversionen erhalten, die im Download nicht mehr zur Verfügung stehen. Eventuell können wir auch bei Bedarf Versionen für ältere MacOS Versionen erstellen. Bitte kontaktieren Sie uns in diesem Fall über die im Impressum angegebene E-Mail-Adresse.
