Review on OpenFOAM by Trevor Blazis

It's easy to use, very stable with great results in simulation of flows; it has been tested by many different companies from all around world that have benefited greatly using this tool! The only thing I dislike about OFPMA was its license model which made me think twice before buying licenses - but now we are happy because they changed their licensing policy so as not be restrictive anymore like other softwares do nowadays!! We're solving problems related water distribution networks modelling such us flow direction control valves sizing etc..
