Switch from single precision to double precision
 
Dear all,

I run OpenFoam on a Ubuntu 9.10 64-bit computer. It runs with double precision
and I would like to switch to single precision. I changed my etc/bashrc file to

Code:

# WM_PRECISION_OPTION = DP | SP
: ${WM_PRECISION_OPTION:=SP}; export WM_PRECISION_OPTION

and set the environment variable to WM_PRECISION_OPTION to SP. Then i complied the sources :
Code:

./Allwmake
OpenFOAM stills runs with double precision. Can you please tell me what I did wrong ?

Best regards,
Camille
