OpenMDAO - Multidisciplinary Design Analysis and Optimization

OpenMDAO is an open-source (why?) Multidisciplinary Design Analysis and Optimization (MDAO) framework, written in Python. You can use it to develop an integrated analysis and design environment for your engineering challenges.

In layman’s terms: OpenMDAO is a piece of software that links other pieces of software together. It allows you to combine analysis tools (or design codes) from multiple disciplines, at multiple levels of fidelity, and to manage the interaction between them. OpenMDAO is specifically designed to manage the dataflow (the actual data) and the workflow (what code is run when) in conjunction with optimization algorithms and other advanced solution techniques. OpenMDAO also has extensive optimization capabilities built right in.

SPEIC14 is the scientific conference on Combustion and related fields, Lisboa, Portugal, November 19 to 21, 2014

Following the very successful SPEIC10 conference on the island of Tenerife (Spain), the SPEIC14 conference will be held at Instituto Superior Técnico, Lisboa, Portugal, from November 19 to 21, 2014.

SPEIC14 is the scientific conference on Combustion and related fields, jointly organized by the Portuguese and Spanish Sections of the Combustion Institute.

The first conference took place in the island of Tenerife (Spain), on 16–18 June 2010. The Conference was attended by around 100 researchers from over 20 countries and 4 continents. It featured 5 Keynote Lectures, and about 70 contributed papers.

The 2014 edition of SPEIC will serve the additional purpose of honoring Professor César Dopazo and his scientific leadership in the fields of Fluid Mechanics, Combustion and Energy

The Conference will address the following topics, with a special emphasis on sustainable combustion:

•         Reaction kinetics, and large-molecule (soot, PAH, dioxines) phenomena

•         Flame theory, experiments and calculations of laminar and turbulent flames, single or multiphase.

•         New diagnostic techniques

•         New computational methods

•         Sustainable combustion: Oxy-combustion, chemical looping, hydrogen and syngas combustion, biomass combustion, mini- and micro-combustors, and other novel combustion processes.

•         Combustion systems: ICE, gas turbines, furnaces

•         The ignition and propagation of fires in the natural and built environments.

matplotlib: free plotting tool in Linux, (python code) similar Matlab

matplotlib

matplotlib is a pure Python 2D plotting library designed to bring publication quality plotting to Python with a syntax familiar to MATLAB users. All of the plotting commands in the pylab interface can be accessed either via a functional interface familiar to MATLAB users or an object oriented interface familiar to Python users.
The library uses numpy for handling large data sets and supports a variety of output backends including GTK GTKAgg, GTKCairo, FltkAgg, QtAgg, TkAgg and WXAgg.

 Features include:

• Generate:
• Plots
• Histograms
• Power spectra
• Bar charts
• Errorcharts
• Scatterplots and more
• Based on Python, a full-featured modern object-oriented programming language suitable for large-scale software development
• Suitable for fast scripting, including CGI scripts
• Free, open source, no license servers
• Native SVG support

Installation guide:

Install in ubuntu/debian:

- sudo apt-get build-dep python-matplotlib 

Install in Fedora/Red Hat:
- su -c "yum-builddep python-matplotlib"

- cd python folder
- python setup.py install

Solve license server and client problems

By default, the FLEXlm license manager will use random ports chosen whenever it's started. To use a static port number for the communication between Maple and the FLEXlm license manager, the following changes will need to be made:

On the server (maple.lic) – add the static port number to the end of the SERVER line. For example, if you wish to always use port 27000:

SERVER [servername] hostid 27000

On the clients (license.dat) – add the static port number to the end of the SERVER line. In this example, the license.dat file in the Maple license folders would look like:

SERVER [servername] ANY 27000

USE_SERVER

Once a static port number is chosen the firewall can be configured to allow communication on this port.

There is a second port number used on the license server itself for communication between the FLEXlm license manager and the maplelmg vendor daemon. This is not usually an issue, since firewalls typically do not block communication on the local machine. However, if you would like this port number to be static as well, you will need to make the following change on the server only:

On the server (maple.lic) – add the second static port number to the end of the VENDOR line with the port option. For example:

VENDOR maplelmg PORT=27010

The first change will ensure that FLEXlm always uses the same port number to communicate with the Maple installations. The second change will ensure that the same port number is used internally on the license server for the communication between FLEXlm and the vendor daemon. Please ensure that your server's firewall allows connections on these two ports.

add allowed portal in firewall:  edit /etc/sysconfig/iptables
Add following lines to allow <port> in TCP/UDP
-A INPUT -p tcp -m tcp --dport 27000 -j ACCEPT
-A INPUT -p udp -m udp --dport 27000 -j ACCEPT
