Hi, I know star ccm+ is a high end CFD code covering numerous application areas, but I wander if it is good enough for electronic cooling. The specifics there are: complex 3D geometry, needing "cleaning" before meshing, geometry manupulations (moving, copying, boolean, deleting), cooling fan models, thermal joints, perforated plates/porous medium, turbulent flows, radiation, etc
Are there tutorial video(s) or tutorial pdf files to see: a)how difficult is to build an electronic cooling model and b)solver's performance and accuracy. |

No any comments, so it looks like there is nothing positive to say about the applicapability of star CCM+ for electronic cooling

Hi,
There is a Tutorial about a GPU Cooling with a Fan and GPU heat generation. Also, There is on Youtube a long video of someone doing a doublel CPU Cooling. https://www.youtube.com/watch?v=LCUr2AMqrT0 All the things you mention from radiation, turbulence, fan models, etc etc are possible to do with STAR-CCM+ |

StarCCM+ is a very powerful tool that can be used for many things both in Academia and/or Top Level Industry .
Of course, as most of this tools, the validity of the results you get is proportional to the reliability of your input data. Going back to you initial questions, Can STARCCM+ do... - complex 3D geometry, needing "cleaning" before meshing: Yes - geometry manupulations (moving, copying, boolean, deleting): Yes - cooling fan models: Yes - thermal joints: Yes - perforated plates/porous medium: Yes - turbulent flows: Yes - radiation: Yes Are there tutorial video(s) or tutorial pdf files to see: a)how difficult is to build an electronic cooling model: Difficulty will be highly dependant and you input data/files b)solver's performance and accuracy: As accurate as you input model / data is |

It works fine. Name any possible reason - why it wouldn't be good for electronic cooling.

My concerns are related to cleaning and successfully meshing complex geometries with hundreds of (essential) solids, having various shapes and sizes as well as to solver convergence when dealing with hundreds of heat sources, simultaneous external and internal flows/heat transfer, simultaneous gas and liquid cooling, porosities, fans and a few other specifics related to electronic cooling. |

Your initial question wasn't any bit specific either

So basically I (and its not just my opinion) would say - time spent on working on 3D model in Star should be reduced to as little as possible. Personally I clean geometry with SpaceClaim, although it would be more handy to use NX (there is a live-link between, thus no need for export/import in neutral formats) or Solid Edge (still waiting for live-link to it in Star).

The thing is that Star as a tool is pretty much sophisticated and customizable if you dig deep - and the deeper you dig the more possibilities and features you find. In some ways Star is like a "To build a house you have first to collect some clay and fire the bricks" - some basic things have to be implemented manually, but again - the flexibility is great, giving you an opportunity not just "to build a house" but also to "mine some iron and uranium ore and to build the nuclear reactor next to your brick house". There is also a way to automate it with macros. |
