i dont suppose, any1 out there has got a cfd package, which i could have/borrow/download (will pay for postage and packaging, if necessary) or alternatively, if I send you the cad file give me, a reading from it?


Thanks for any help

hi

i have no spell checker to day sorry.

1. A CFD packeg is all well and good but you are going to need a rengerng engin wicke will display the results as well plus the ability to inport youer CAD file to the CFD format or redo the file.

it is not easy to ues stuff and itis very expencive (think sevral grand plus a work station) to get somthing like fluent or sinergy. gow ever if any one has a copy I can borow I would be intrested.

what I would recomend doing for a locost solotion wright youer owen (I have been working on this for some time and if you whant to hellp have ideras or get involved just say) use one of the 2d program freely avalbel and simulate a lot of slices and compile a 3d modle that way (time consuming) find an american who will sine up to the NASA down load sight send the email and prove himself not to be a teroist download and post the softwher to you (worth doing if you can find some one to do it) but you will need to compile it (if you get the source I can compile it for you)

CFD is valueless unless you have exprimental data from a very similar flow stituation to sanity test the results. I spent 12 months working with Fluent modeling annular diffusers -- the first 6 months of which were spent just setting it up the boundary conditions replicated from known experimental data.
CFD software is much more difficult to use than structural FEM/FDM modeling because the initial inlet flow conditions, turbulence, velocity profile and boundary layers are much more complex than mechanical BCs

Don't know if it's what you're after but they do a free trial if you fill in the form. Worth a look.
