Switch from single precision to double precision -- CFD Online Discussion Forums

March 11, 2010, 07:14	Switch from single precision to double precision	#1
kk81 New Member Camille Join Date: Mar 2010 Posts: 1 Rep Power: 0	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
