Generative Models

2011-07-18T17:11:00.016+02:00

Improving Design Development


Jonathan Mirtschin and we recently co-authored an article in the
Taiwan Architects 2011.07 magazine.
Below the original article in mandarin and english.

also featured in the article academia work by 4th year students 
Benjamin Ennemoser and Philippe Grotenrath.
University Innsbruck/Austria exparch.hochbau 2011.


As performative design concepts become more accessible to 
designers, we will see more analysis tools being developed 
for the design process. As we establish methods for understanding 
surface-based-analysis, we will be moving into volumetric-base-
analysis.

Generative tools such as Grasshopper3d (Robert McNeel Associates) 
and Maya (Autodesk) are being utilized to explore architectural 
projects and inform design decisions with increasing popularity. 
However, rapidly produced multitudes of options will not be 
utilized to full potential if entire design team assessments take
days or weeks to fulfil. To maximise the potential of these tools, 
teams must efficiently assess multiple objectives and criteria, 
to seek optimal solutions. Utilizing the generative information 
model as input to analysis and simulation tools (including structure, 
services, environmental, construction programming and
cost assessments) can facilitate superior design decisions.

This article outlines and demonstrates software developments 
enhancing Grasshopper3d as a generative design tool for the 
architecture and construction industry. Additional functionality 
enables designers to assign attributes of design elements that can 
be utilized in exporting the information model for wider design 
consideration. Present industry practises where multiple models are 
independently created require consuming efforts in updating and 
coordinating. Duplicated, abortive and redundant design efforts 
are rife, and given the time consuming nature of these tasks, 
the potential to improve and assist these procedures is enormous. 
There is scope for substantial improvements for this process in the 
earliest phases of design, when identifying the strongest concepts 
can have the greatest impact on the final product and the least 
constraint is experienced to change.


Structural Analysis


Generative modeling for developing structural analysis models has been prevalent for years, primarily in the
form of authoring spreadsheets. Geometrical description using imports 
such as DXF or DWG cad models have also been used extensively, 
although this process typically requires manual application of 
analysis attributes not supported such as constraints, materials and 
loads. Evaluation of performance relating to alternate design scenarios 
is accelerated by producing in bulk the structural analysis attributes 
as related to the generative model. This is shown for the 3-dimensional 
proximity truss structure as a Structural Analysis with 
Geometry Gymplugin for Grasshopper and Oasys GSA


Building Energy Analysis


Ecotect is a highly visual software for architects to work with 
environmental performance issues. It is designed for early stages of 
conceptual design, and encourages play to understand environmental 
factors and interactions. Ecotect works on the principle of 
“progressive data input”, that means that it is prepared to give
visual feedback even with very little information. Not all aspects 
of a scenario have to be spelled out in detail.
In fact the simulation can be done earlier, and as the model is refined, 
results become more accurate. 
GECO is a Grasshopper plug-in developed by [UTO] that offers a direct 
link between Rhino/Grasshopper models and Ecotect. 
The Plug-in allows you to export complex geometries very quickly , 
evaluate the design in Ecotect and access the performances data, to 
import the results as feedback to Grasshopper.
This could be done as single process or loop to improve performance 
and the design of a building in the context of its environment.
The single results of the process could be saved inside Rhino in the 
vertices of the analysis mesh to store data
for later use inside different design approaches.

NEXUS workshop

2010-08-25T11:00:00.015+02:00

grasshopper advanced workshop

TIME AND LOCATION

27th – 29th September 2010
Leopold-Franzens university innsbruck/austria
Technik Campus | ICT - building
Technikerstraße 21a
A - 6020 Innsbruck | Austria
47°15’50.71”N 11°20’43.45”E

detailed program as pdf-version

The focus of the workshop is to integrate and correlate the synergistic effect associated with simultaneous presence of different digital design- and analysis tools in an ongoing design process.The main attention is set on easy to handle interface , which should be used at a early stage of conceptual design to respond to external and internal influences in a intelligent and sustainable way.

Participants will use the software Grasshopper as a parametric modeling plug-in for Rhino. The usage of this graphical algorithm editor tightly integrated with Rhino’s 3-D modeling tools open up the possibility to construct highly parametrical complex models. To generate this complexity we will use live linkages to several programs listed below:

• Autodesk Ecotect Analysis and Radiance via GECO
• Processing, Excel or Open Office via gHowl
• FEA software GSA via SSI

In this 3 intense days, the participants should learn the workflow of the plug-ins with the help of examples and get an overview of the different software’s, there possibilities for evaluating the performance of a design or the usage of additional tools to be not chained to a single system .(e.g. parametrical accentuation, parametrical formation, parametrical reaction)

DE

Der Schwerpunkt dieses Workshops liegt einerseits in der Integration und andererseits in der Korrelation verschiedener Synergieeffekte, die sich aus dem gleichzeitigen Vorhandensein aus digitalen Design- und Analysetools im Entwurfsprozess ergeben.Besonderes Augenmerk wird dabei auf eine einfache Handhabung der verwendeten “Schnittstellen” gelegt, um bereits in einem frühen Entwurfsstadium besser auf interne und externe Einflüsse reagieren zu können und somit zu effizienteren Lösungen zu gelangen.

Die Teilnehmer werden unter Verwendung eines algorithmisch parametrischen Modellierungstools von Mc Neel, genannt Grasshopper interaktive parametrische Modelle für komplexe Geometrie erarbeiten.
Unter anderem wird dabei eine Echtzeit -Verbindung zwischen Grasshopper und folgenden Programmen hergestellt:

• Autodesk Ecotect Analysis bzw. Radiance über Geco
• Processing, Excel bzw. Open Office über GHowl
• FEA Software GSA über SSI

Im Rahmen dieser 3 aufeinander folgenden, intensiven Workshop-Tagen wird den Teilnehmern anhand von Beispielen in erster Linie die Arbeitsweise der Plug-Ins bzw. Schnittstellen erläutert (Workflow) und zusätzlich ein Überblick über verschiedene Softwaren, die auch im Rahmen des Workshops verwendet werden, verschafft. Dies soll vor allem dazu dienen, deren Stärken in der Entwurfsmethode aufzuzeigen (z.B. parametrische Akzentuierung, parametrische Figuration u. parametrische Reaktionsfähigkeit).
