Hello Everyone,


It has been a while since I posted in CFD online. I am looking for experts suggestion. For electronics cooling (mostly conjugate heat transfer) which is most suitable in terms of:


1. Less elements but still predict heat transfer from fins accurately in otherwords predict thermal resistance of heat sinks accurately.


2. Robustness


3. Stability


Thank you in advance.



Best regards,
Naresh Yathuru

I work with Autodesk so am of course biased and can in fact only comment on our solution.
We should have no issues here though, should be pretty simple. That is about all I can say, give it a go

Forget about Autodesk. It is expensive, unreliable and buggy especially when you deal with relatively complex models. SW Flow simulation is much better option for electronic cooling especially if you use SW as your 3D mechanical package.

The best option however in my opinion would be HeatDesigner or scStream from MSC Inc although they will be more expensive than SWFS (but cheaper than Autodesk CFD).

P.S. I don't work for any software company and I don't use any of these packages anymore but used them extensively in the past when they were called CFDesign and Floworks.

I have struggled lot by referring the paper called AEROTHERMODYNAMIC ANALYSIS OF MANNED SPACE VEHICLE that is written by Author GUIZEPPA PELLAZA and ANTONIO VIVIANI.
They did this Simulation using ICEM-CFD toolbox and surface impact method(SIM) BY CIRA.I have to compare this paper results with ANSYS FLUENT toolbox.Eventhough I give Proper boundary conditions from this paper and implementing Chemkin file,Iterations are not starting.What Can I do with simulation of this MPS using Chemkin file?I HAVE ATTACHED THE CASE FILE WHICH I DID.I given boundary conditions like
inlet,oultet and wall- pressure far field
Space capsule-interior
PRESSURE-1400pa
Temperature-560k
angle of attack 20 deg for space capsule
Mach number-20
