Hello,

I am trying to see if I can export unsteady CFD data using "auto export" feature in Star-CCM+ multiple times each time step without re-running the CFD model multiple times. The purpose of this is to test the compatibility of other software packages, and I hope to get it done relatively simply.

I've tried in GUI, but it seems that Star-CCM+ allows only one instance of "auto export" in GUI. Is it possible to do it via scripting? Any help/advice will be very appreciated.

Thank you!

There is special section on co-simulation with "coupling with CAE codes". There co-simulation tutorials are available under guide for softwares like GT-Suite, Abacus etc. Is something like this are you looking for?

Hello,

No, I am not interested in using co-simulation directly. I have my own workflow and I want to stick to that by having data exported.

Thank you for the suggestion, by the way.

Sincerely,

Hi, I would suggest recording a macro as you do the exports manually in the GUI. The resulting block of code can then be edited as required and then invoked at appropriate places during the solution. So this would require to execute the solution through a macro rather than the GUI. Here are a few useful commands that can be used for this purpose (sorry if you know all this already).

Simulation simulation_0 = getActiveSimulation();

simulation_0.getSimulationIterator().iterate(1, true); // run one iteration
simulation_0.getSimulationIterator().run(3, true); // run three time steps
simulation_0.getSimulationIterator().run(); // run until stopping criteria are satisfied

Hi FliegenderZirkus,

Thank you! I haven't thought about the option of manually exporting files each step. I think that it makes sense. I'll update this post after trying it.

Thank you!

UPDATE: Yes, it is working. I should try to figure out how to manipulate the names for boundaries, regions, and so on in more a programmatic way.
