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 https://bauklimatik-dresden.de/software/ccm-editor/ccm-faq-hilfe/)

• 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 https://bauklimatik-dresden.de/software/mastersimulator/).

• 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:

  • https://bauklimatik-dresden.de/software/postproc2/postproc2-dokumentation/
  • https://delphin-simulation.com/delphin-en/6.1.7/tutorials/python_scripting_01.html

• 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 available on the DELPHIN download page: https://bauklimatik-dresden.de/software/delphin/delphin-download-lizenz/

This is not done automatically, to avoid data loss when using old/new DELPHIN versions at the same time.
