I am looking for software called "phoenix" but i do not know if it is the vendor- or the softwarename. Thanks in advance, Frank-Peter

You probably mean Phoenics. It was one of the first general purpouse CFD codes, developed by Prof Spalding and his co-workers at CHAM (Concentration, Heat and Momentum Ltd). They might distribute older versions as shareware, one very old version even includes source code. You can find further information at their web site located at http://www.cham.co.uk.

Hope that helps.

if you are looking for PHOENICS " Parabolic, Hyperbolic Or Elliptic Numerical Integration Code System" you can get the shareware version from this adress. http://www.cham.co.uk/
