Tutorials DELPHIN
The instructions listed here should make it easier to get started with DELPHIN.
Tutorial 1 – Creation and editing 1D
This example shows the basic process of creating a project in DELPHIN. The necessary steps for setting up a simulation for the hygrothermal evaluation of the construction before and after the renovation are explained on the basis of an old building’s outer wall that needs to be thermally improved. This tutorial is intended as an introduction to DELPHIN and is suitable for getting to know the most important features
Tutorial 2 – Creation and Editing 2D
This tutorial builds on the basics shown in the 1st tutorial. The focus of this guide is on the modeling of two-dimensional construction details. Using the example of a thermal bridge, it is shown how to enter a 2D construction, define and assign boundary conditions for the various surfaces of the construction, and specify outputs. The special features of flow outputs (e.g. heat flows) are also described.
Tutorial 3 – Result analysis with PostProc 2
This tutorial demonstrates the typical work steps involved in using the post-processing tool PostProc 2 to analyze the calculation data.
Tutorial 4 – Outputs in DELPHIN 6
This tutorial explains in detail how outputs are defined in DELPHIN, what options exist and what output is required for damage assessments.
Tutorial 5 – Assessment of constructions
The current state of design evaluations is shown here. What assessments exist and what do the standards say about them. Then, examples will show how these evaluations can be implemented in DELPHIN from version 6.1.5.
Tutorial 6 – Climate data
This tutorial explains how to handle and use climate data. How do I select climate data for the site and how do I create and use my own climate data.
Tutorial 7 – 3D modeling with DELPHIN 6.0
This tutorial explains how three-dimensional simulations can be created and evaluated in Delphin 6.
Tutorial 8 – Editing materials with DELPHIN 6.1
This tutorial explains the material editor in DELPHIN 6.1. The functions for changing material data will be explained and finally deepened by means of 3 examples. The following scenarios are used:
- Hydrophobization of a masonry brick
- Adaptation of a database material to existing measured values (existing bricks)
- Make material permeable to air – add necessary material parameters
Tutorial – Material selection from the database in DELPHIN 6.1.2
This tutorial explains the material editor (DELPHIN from version 6.1.2). This is mainly about the filtering functions to make it easier to find materials. This also applies to the search for materials that are similar to known material data. Finally, the handling of user materials is discussed.
Tutorial – Air leakage source according WTA 6.2
Description of the generation and assignment of a moisture source for leakages according to WTA 6.2 or DIN 4108-3 D.
Tutorial – Contact conditions
Description of the generation and assignment of contact conditions. These are used specifically for modeling vapor retarders. It is therefore not necessary to add these as material layers.
Tutorial – Base plate
This tutorial describes how to simulate a floor slab in a simplified way in 1D using the correct soil conditions. For this purpose, the temperatures in the soil are precalculated using a 2D thermal calculation and then used further.
Tutorial – Lightweight wall
This tutorial explains the procedure for simulating a timber stud wall. This wall is first simplified in 1D and then calculated as a 2D detail. Among other things, the following points are discussed:
- Modeling of rear-ventilated areas
- Use of the leakage source according to WTA 6.2 or DIN 4108-3 D
- Assessment of timber components in 2D constructions
- Use of vapor retarders as contact conditions
Tutorial – Wall heating
This tutorial shows different variants of modeling a wall surface heating system using the DELPHIN raw model. The use of your own climate data is also discussed.
- Installation of a 1D wall construction
- Extension to 2D for the installation of wall heating pipes
- Explanation of the pipe model
- Use of own climate data for a model (flow temperature of the wall heating)
Special topics, tips and tricks
With various methods, DELPHIN can be used much more efficiently and extensively than it seems possible by using the user interface alone. A few ideas for this can be found in the tutorials and HowTos listed.
Automated variation and sensitivity studies through scripting
This guide shows how the automatic processing of many simulations can be further improved and accelerated with the help of simple Python scripts (a very light script programming language). It is shown how variation studies can be carried out very efficiently on several processors on modern multi-processor machines. The tutorials also contain links to example scripts (Python 2.7 and Python 3).
Use of FMI co-simulation (FMI export of DELPHIN models)
The guide below explains how DELPHIN can be used within an FMI co-simulation environment. DELPHIN can export a specific project as an FMU, which can then be used by an FMI master program (see also MasterSim).
