Experiment



In the last decade fire science and fire engineering have grown thanks to the continuous progress of computational fluid dynamics (CFD), both in the field of theoretical modeling of physical phenomena and in the field of technological implementation of these models through the use of complex algorithms and thanks to the grown power of modern computers.

Fire Dynamics Simulator (FDS) is a model developed by National Institute for Standard and Technology (NIST, USA) that simulates fire and predicts its effects; in the package a graphical post-processor Smokeview is included for FDS results analysis.

FDS is widely used by fire safety professionals. FDS was also used in numerous fire reconstructions including the investigation into the World Trade Centre disaster.

Fire and Smoke SimulationFDS simulations with a real scenario represent long-time,

computational intensive and memory consuming jobs.

In order to find the programming model exhibiting the best performance and producing authentic true results for a given fire scenario, a great number of experiments, i.e. simulation runs with various input parameters, need to be fulfilled.

The parallelization requires a decomposition of computational domain into computational meshes, which affect the simulation outputs.

In order to use MPI version of FDS, computational domain must be decomposed into meshes and each one of them can be assigned to specific MPI process.

We have partially realized the FDS simulation of a 180m long test tunnel on the cluster (video room, tunnel).

Experts for running FDS simulations on the Grid are welcome.

Project goals

This Virtual Team aims to establish a fire and smoke simulation Virtual Research Community on EGI by

• Porting three types of parallel implementations of the FDS application to the European Grid Infrastructure.

• Identifying user communities for the ported application. • Providing support for the communities to use the FDS

application on EGI.• other fire simulation applications tests for other types of

fires, e.g. forest fires are welcome• …

Fire and Smoke SimulationThe expected output of this project are:• Parallel implementations of the FDS application on the European Grid Infrastructure, together

with guides for users and software administrators.

• A European community actively using the FDS application on EGI.

• Support services provided for the FDS user community in multiple NGIs.

• Similar outputs could be formulated for Forest fires simulation, …

The required output for the project will be achieved by the following tasks:

1. Contacting fire simulation teams within the NGIs and collecting input requirements from them for the EGI-enabled version of the FDS application

2. Porting three implementations of the FDS application to EGI according to the users' requirements:

• MPI application

• OpenMP application

• combined MPI-OpenMP application

3. Implementing different simulation use cases on EGI with the FDS application; analyzing the results with the SmokeView visualizer tool

4. Developing training for fire and smoke simulation communities

5. …

6. Developing a marketing and communication plan to undertake the outreach to the fire simulation community at their events

Fire and Smoke SimulationExperiences with working in the VT framework

• We have contacted the fire simulation experts from Slovakia with experiences in usage of advanced fire simulators.

• The experts from abroad are welcome.

Members: • NGIs - confirmed: Slovakia• EGI.eu: Gergely Sipos

The Portuguese group (António Pina, Jorge Gomes, Tiago Sá, Antonio Esteves, vitor Oliveira) working in Fire Simulation is willing to join the Virtual Team recently formed to explore this kind of work. They would like to join the first meetings and see if the work which will be done under this VT is aligned with their own goals, and then reassess their interest afterwards.

Fire and smoke simulation can be a priority topic in the Mediterranean countries (Isabel Campos, Marios Chatziangelou, Kostas Koumantaros, Daniele Cesini, Onur Temizsoylu).

Current status and next steps

• we have proposed a VT project 'Fire and Smoke Simulation' • a requirement and a prepared information was sent to G. Sipos,

who created for us a webpage• we have organized a telco to clarify main goals and tasks of the

VT project with partners that displayed preliminary interest to participate in it (http://www.doodle.com/wg288ngziz68suw8 , http://evo.caltech.edu/evoNext/koala.jnlp?meeting=M9MIMi2D2lDvDi9I9BDD99 )
