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.

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

Flow Vision, CFD multi-purpose simulation

FlowVision CFD system

FlowVision is a new generation multi-purpose simulation system for solving practical CFD (computational fluid dynamics) problems. The modern C++ implementation offers modularity and flexibility allowing addressing the most complex CFD areas. Unique approach to grid generation (geometry fitted sub-grid resolution) provides natural link with CAD geometry and FE mesh. The Abaqus integration through Multi-Physics (MP) Manager supports the most complex fluid-structure interaction (FSI) simulations (e.g., hydroplaning of automotive tire). FlowVision integrates 3D partial differential equations (PDE) describing different flows, viz., the mass, momentum (Navier-Stokes), and energy conservation equations. The system of the governing equations is completed by state equations. If the flow is coupled with physical-chemical processes like turbulence, free surface evolution, combustion, etc., the corresponding PDEs are added to the basic equations. All together the PDEs, state equations, and closure correlations (e. g., wall functions) constitute the mathematical model of the flow. FlowVision is based on the finite-volume approach to discretization of the governing equations. Implicit velocity-pressure split algorithm is used for integration of the Navier-Stokes equations. FlowVision is integrated CFD software: its pre-processor, solver, and post-processor are combined into one system. A user sets the flow model(s), physical and method parameters, initial and boundary conditions, etc. (pre-processor), performs and controls calculations (solver), and visualizes the results (post-processor) in the same window. Any time he can stop calculations, change the required parameters, and continue or recommence the calculations. Capvidia/ТЕСИС develops two versions of the software: sequential FlowVision 2.xx.xx and parallel FlowVision 3.xx.xx (or FlowVision-HPC). Both systems employ modern technologies of CFD and computer graphics. Source: http://www.fv-tech.com/content/view/125/72/lang,russian/

S3D - Sandia 3D Direct Numerical Solver for combustion

S3D is the Sandia 3D Direct Numerical Solver, which presently is capable of generating tens of terabytes of raw data per run in a parametric study of several runs, presenting a significant challenge for subsequent analysis and interpretation. The current approach is to store the raw data at prescribed time intervals, and then either analyze it on a supercomputer or access it via a local analysis and visualization cluster at Sandia. The raw data is archived so that various modeling groups in the combustion community can interrogate it to test model assumptions. To understand the correlation of scalar fields such as temperature, mixing rates, and species concentrations in turbulent flames, scientists must be able to visualize two or more scalars simultaneously. Conventional visualization tools do not directly support such a capability. Scientists often must make side-by-side comparisons of images of different variables by hand, which is tedious and time-consuming. Furthermore, the information that scientists can derive by looking at separate images is quite limited. Thus, they need effective methods for simultaneously visualizing multiple time-varying variables from large data sets in an interactive fashion.
