computing wall heat flux
 
Hi,
I did simulation for turbulent flow over heated flat plate (constant temperature).
"buoyantBoussinesqSimpleFoam" is used as solver. I get following error by using "wallHeatFlux" utility :

Reading g
Reading thermophysical properties



--> FOAM FATAL IO ERROR:
cannot find file

file: /home/http/OpenFOAM/http-2.1.1/run/plate_new/constant/thermophysicalProperties at line 0.

From function regIOobject::readStream()
in file db/regIOobject/regIOobjectRead.C at line 73.

FOAM exiting



For "buoyantBoussinesqSimpleFoam" solver we have "transportproperties" instead of "thermophysicalproperties"in the constant folder. Then why is it showing this error?

i guess wallheatflux utility works only for solvers with 'thermophysicalproperties' file.... can anyone tell wat is difference b/w "transportproperties" and "thermophysicalproperties"

The first file is used for incompressible solvers while the second one is used for compressible solvers. Different thermodynamic models are used.

den why is wallheatflux utility not working with transportproperties??
