Hello,

I am a user of sc tetra cradle for CFD calculations (Pressure drop, FSI, VOF...) I would like to know your opinion about the software in comparison with others.

Cordially;

I've used scStream and found it excellent.

Hello,

Thx for feedback

Hi
Excellent in meshing and solving , but have little accuracy than Fluent.

It is a very broad statement. Do you have something concrete in mind, like the application area, result comparison with Fluent and the practice, etc?
If you based your statement on just comparison with Fluent, then it doesn't mean much (since Fluent could be wrong).
I used scStream for thermal simulations and found the simulated temperatures to be within 5% of the reality. If Fluent produces much better (and proven) accuracy that would be excellent, but I kind of doubt that.

Hi
I agree with you, i hope that he can show us an example of his results
Thnx

Pardon , do you mean the deference between experiment and scStream simulation result is about 5%???. It should be near the experiment and error be about less than 5%.

I workewd with Fluent for 4 years for an ANSYS reseller and now working with Cradle products (mainly scFLOW, which is sc/Tetra successor) and not only accuracy is comparable (even better sometimes) but the solver is far more stable and faster than Fluent.


Obviously, everyone has its own qualities. Example, Fluent is very good in combustion sim, capability that Cradle has simply developed less, but try to use Overset mesh in Fluent and in scFLOW and then we talk about who's better...

Hi


Realy I used 3 softwares for my thesis. First i used Fluent. It required high cost hardwares, and the results was acceptable. Seconde i use comsol multiphsics. Comsol wase acceptable in result and was easy to mesh and controlling data. Third i used SC/tetra and S/C flow. Sc/Flow hase problem of corant number in high speed and high temperature, but it had agod polygon meshing it was very good. SC/tetra was legned. For the first time i saw the accuracy by my eyes. It was clear mor accuaret than fluent and comosol, and excellent meshing and selecting more mesh dence around the model.

Thanks for all just i tried to share my experiences.
