are there platforms similar to iMechanica? should we list them all?
I think it would be useful to collect a list of most useful sites, to start with iMechanica-look-alike. Not exactly similar but a good site for CFD is http://www.cfd-online.com/. This incidentally suggests us some "ways" to improve iMechanica. (see my other blog PROPOSAL for iMechanica node/2996)
