Export data issue with STar CCM+

mona.16nitr · March 19, 2015, 01:10

Hello.
I am using STar CCM +. Somebody please help me with how to export the temperature values on the outlet face of a geometry. I want to provide this temperature as an inlet condition to another simulation.

Thanks.

Tools > Tables, right click and select New > XYZ Internal Table. Then select the face you want to extract data at in parts and select the scalars you want to output. Then right click Tables > XyzInternalTable and select Extract followed by tabulate. You can then save this in .csv format and bring it in as a File Table in your new analysis. Just make sure that the face your are copying to is in the same location as the face you copied from.

There is also an r internal table that gives scalar as a function of r for axisymetric flows.

Thank you so much for d response ! It helped.

In addition to MBdonCFD table strategy, does anyone knows if this is possible via a co-simulation?
If for example, the temperature profile changes at every time step at the outlet of the first simulation? We could do a macro to export the table at every time-step, but do you know if this can be achieve by a co-simulation?
Thanks

Unless I fail to grasp what you are trying to do, it seems like that is the very definition of co-simulation. Although, I have never used it. The help files say this:

'STAR-CCM+ allows you to couple two running simulations together in a co-simulation analysis. The STAR-CCM+ to STAR-CCM+ co-simulation capability targets simulations involving conjugate heat transfer (CHT), fluid-structure interaction (FSI) or exchange of scalar/vector fields across a coupling boundary.'
