Co-simulation


CADLink Toolkit CFDLink FlowmasterLink for MATLAB

CFDLink

You can easily connect your FLUENT or STAR-CD models to Flowmaster with CFDLink, a client-server utility that operates over communications networks, providing true co-simulation with data integrity at each time-step. You have the full capability of both products available to you. Flowmaster predicts temperatures, pressures, flow rates and many other performance parameters throughout your system model, while FLUENT or STAR-CD can give you velocity vectors, local heat transfer coefficients and much more. You are assured of accurate simulation of your system simulation and 3D coupled models by complete solutions at all common boundaries.

With CFDLink you get a simple, convenient user interface to set up, and run co-simulations with FLUENT or STAR-CD and Flowmaster computations on different processors - truly distributed co-simulation.

CFDLink provides you with:

  • A single, easy to use graphical user interface
  • Definition of Flowmaster project, model and simulation
  • Definition of FLUENT or STAR-CD model and host
  • Specification of start, stop and convergence criteria
  • Execution of Flowmaster simulation on Windows NT
  • Execution of the FLUENT or STAR-CD simulation on a Unix platform in single and multi-processor modes
  • Extensions to the FLUENT or STAR-CD user interface to support the co-simulation

CFDLink allows you to set up the co-simulation from a single user interface by completing a number of data forms. The two simulations then run on the most productive platform for each; Flowmaster on Windows NT and FLUENT or STAR-CD on one of a number of supported Unix platforms. The utility manages all data-flow between the simulations, including format conversion.

Case Studies

BMW Motoren, Steyr couples 3D CFD with Flowmaster system simulations

BMW Motoren GmbH, Steyr, combine 3D CFD with system simulations to analyse the cooling system of a six-cylinder automotive diesel engine. They found that results of the co-simulation were an improvement over the independent analyses. The results show that the original assumptions were inaccurate and that the original design had been sub-optimal.
