do anyone use solidwork 2009 to run simulation

Sw 2009 improve the feature of flow simulation compare with SW 2008, so anyone try to use SW 2009?

Yes I've Worked with it.

isint good? almost same with EFD flow?

hi.In fact it does not have many differences with other versions.but sometimes its results are different form the previous versions.For example I simulated a VAWT with cosmos 2007 and FloEFD (SLD 2009) but the results were not the same.even the results of the cosmos 2007 were more reliable.

SW 2009 only can analysis 1 fluid? nw i going to analyse cooling tower, it need air and water 2 fluid. i try in SW 2009, but it only can input 1 fluid.

Hi kacee,
No Flow Simulation (FloWorks) or also FloEFD cannot simulate two-phase flows. Each phase (liquid or gassious) has to have it's own seperate domain. So simulations such as sea waves or in general free surfaces are not possible.
Differences in the results may occure due to code enhancements. One simply cannot say the first results are better than the ones with the other version. Simulations will always have a variation of the results. You could be 5% off from measurements with the older version and -3% off with the newer version, the newer version might be 8% off from the old version but is closer to the measurements. Of course the code can be improved and give better results in the one case but also a bug could cause worse results or a change in the code that would improve results for one simulation case could give worse results in the other case. This is not intended and unwanted but developers simply cannot test all possible scenarios. There are millions of different cases for simulation but if you can show the results became much worse than in an exceptable range that can be understood as normal fluctuations I'm sure the developers would like to see that case and find out why to improve the results in such cases in one of the next versions.
So simply contact your support if this happens and let them try to find the problem and help you.

when the result come out, it show velocity, if i wan temperature, how to change it?

You can change it in the view settings.
But you really should work with the tutorials, it's all explained in there.

You can change it in the View Settings under the tab contours. Either go there via the button or double click on the colorbar. You can also go with your mouse over the parameter below the colorbar then it will become highlighted and you can click on it to get a dropdown where you can select the parameter you want and apply it with the green hook or check symbol.

I can only repeat, work with the tutorials it will help you understand more than just how to click a button. Of course some may think tutorials are for babies but do you know how the minimum gap size is defined automatically by FloEFD or FlowSimulation? It's mentioned in there, also how to work with the mesh instead of simply setting it to Level 8. Trust me, if you didn't have a training it is definitelly woth it. FloEFD or FlowSimulation is easy to handle but there are still tricks and tips that are not quite obviouse. It's a difference between beeing able to click some buttons and get it to run and to understand how to improve the mesh to reduce calculation time and still get great results.
