Models

Calculation speed

Simulationen in external workstations/servers

Overview

Dresden, 07/29/2020 Slide 2

Webseite with climate data infos:

https://bauklimatik-dresden.de/climatedata.php

Preview of climate data of currently

selected location and selection from

database in tree view

Funktionality:

Filter

Direct use of climate data in different formats (c6b, wac, epw)

Colored identification of available data (e.g. green = rain/precipitation)

Climate data preview and importImport of own data into the user-specific climate database

Dresden, 07/29/2020 Slide 3

Manual reference to own climate data files

• Display of base parameters in Material Reference Dialog

• Simplified material file import: Import into project directory

Only confirmation of target filename necessary

Material file will be copied into project directory, subdirectory materials and referenced relative to project file – suitable for transferring project directories and storage of projects independently of DELPHIN installations

• Duplicate material file…

Useful for creating material variations, afterwards the copied material can be edited in material editor

Material reference dialog

Dresden, 07/29/2020 Slide 4

• Editing materials

Edit with material editor: Edit…

Edit with text editor: Open in text editor…

Tip: with the text editor, many small changes can be made real quick, alsocopies of materials (variants) can be saved

Material reference dialog

Dresden, 07/29/2020 Slide 5

Dresden, 07/29/2020 Slide 6

Functions for adding, editing, copying and removing material files from the database

Material Database

Display of material

functions side-by-

side with the table

• Materials in project (directory) and user material database can be edited

Recommendation: first edit only project-specific materials

• Create new materials via in the material database view:

Recommendation : start from existing, working material and modify this, instead of

starting from scratch

• Input of individual material parameters/functions via tabs

Material Editor

Dresden, 07/29/2020 Slide 7

Primary properties should be

selected first with these flags

(parametrization options

depend on these flags)

• Editing always applies to respective file (same as with text editor)

• Apply and Ok write content of dialog to m6-file

• Manual, see:

https://bauklimatik-dresden.de/delphin/documentation.php

Material Editor

Dresden, 07/29/2020 Slide 8

Remove

redundant/alternative

parametrization in the same

section (only the currently

shown functions/parameters

remain)

To show currently not defined

parameters

(clearing a value removes the

parameter definition)

Mirror operations:

Construction editing/modelling

Dresden, 07/29/2020 Slide 9

Adding rows/columns:

Konstruktionserstellung/Modellierung

• Three variants:

Insert with given size

Insert, such that total size corresponds to given total width/height

Insert through splitting the selected layer

Dresden, 07/29/2020 Slide 10

• FMI Export support for FMI 1 und 2

see https://fmi-standard.org

Every scalar result can be exported

Any climate condition may be imported

Configuration via FMI Export-Dialog:FileExport Functional Mock-Up Unit…

Functional Mockup Interface (FMI)

List of climate definitions, which have

been configured as external Variable

List of all scalar result quantities, either

from output definitions, or from

models themselves (latter with yellow

background)

Dresden, 07/29/2020 Slide 12

• Using MASTERSIM zur Co-Simulation:

See Tutorial: FMI Co-Simulation mit DELPHIN 6DELPHIN_6_Tutorial_FMICoSimulation_de.pdf

Direct import of DELPHIN FMUs into co-simulation scenarios

Several instances of the same FMU may be used concurrently(Example: several soil heat collectors in a district network model)

Functional Mockup Interface (FMI)

DELPHIN FMU, with inputs

and outputs

New models:

VOC/Pollutant source

VOC/Pollutant-Initial condition (adsorbed/gaseous)

Pipe collector model (including support for symmetry)

Temperature-dependend control of energy source:(more complex controls can be implemented via FMI interface)

Modells

Dresden, 07/29/2020 Slide 13

Output definition

(Temperature value/-sensor)

Limiting temperature

and control tolerence

Dresden, 07/29/2020 Slide 14

2D/3D simulations optimised:

• Analysis and optimisation of solver parameters, see publication:

Andreas Nicolai und Ulrich Ruisinger; Untersuchung optimaler Numerikparameter fürdynamische hygrothermische 3D Simulationen unter Verwendung iterativerGleichungssystemlöser; 2020; BauSim 2020, Graz

• Improvement of interaction with external simulation workstations/servers via via Remote Solver Server (RSS) protocol:

Login and job-management directly supported in user interface

Improvements when using servers/workstations shared by several users:

Performance

CCM-Editor – Version 1.0

Import of generic data with import assistant (e.g. from Excel, LibreOffice-Calc , text files, measurement data/data logger files etc.)

Creating cyclic annual data (with hourly values) or files with arbitrary time grids (also several year data)

Visualisation of data and content checks with false-coloring in table columns

Manual: https://bauklimatik-dresden.de/ccmeditor/help

Improvements in external tools

Dresden, 07/29/2020 Slide 15

POSTPROC 2.0

Extensive Post-Processing Tool

Contains now all mold prediction models

Completely replaces previous/old DELPHIN 4/5 PostProc(the old PostProc is no longer contained in the installer)

Support for vector flow field plots added, as well as model calculations

New, extensive documentation: https://bauklimatik-dresden.de/postproc/documentation.php

Improvements in external tools

Dresden, 07/29/2020 Slide 16

Command line tools have been reworked and improved:

• Tools are in DELPHIN 6 install directory (bin-directory) besides Delphin6 and

DelphinSolver executables (in Mac inside App-Bundle)

• CmdDiscretize:

Enables changing of discretization with command line options

Ideal for script-based variant studies with geometric adjustments followed by automatic grid generation

• DSixOutputConverter:

Tool for (pre)-processing DELPHIN result files

Extensive manual:https://bauklimatik-dresden.de/postproc/documentation.php

Conversion

Extractions/Calculations

Mirroring of data

…

Have fun and success in usingthe new DELPIN 6 version for

modeling and simulation!
