hi,

i've written a 2d ns solver and i'm trying to compute the lift/drag of the flow past cylinder/airfoil etc.

i'm written another program to calculate lift/drag but the results are not correct. hence i'm trying to use a software, to determine if its my post processing program or ns solver at fault.

Can anyone recommend a software? commercial or freeware. my university might 've it. main objective is to find lift/drag.

thanks!

I agree with him.

but what is the data format of the paraview

wow, Paraview supports a bunch of file formats, including a raw format. Take a look in http://www.paraview.org/Wiki/ParaVie...iew_support.3F

I personally use Ensight's format and the Fortran routines there I've been using are available in http://www.nacad.ufrj.br/~rnelias/pu...anRoutines.zip

Cheers
