Hi Foamers,

I have a Doubt, i an unable to get Y+ for prism model in sonicTurbFoam i have also tried to download and put Make and checkYPlusCompressible.c file in wall directory.under utalities.Still it is not working

the error i am getting is :
Command not found

Can any one help me in this regard

Thanks

Hi, did you used "wmake" in the folder?

Bye

Hi actually i found the problem, i have OpenFOAM 1.5
and i have to use yPlusRAS command but now i am facing other problem
i m not having Transportproperties Directory for Prism case in sonicTurbfoam can any one sand it to me

i also want to know how can i know what is the density of air and value of mue taken for calculations.

please halp me in this regard

Hi Fomerss,

now i am having some other problem while running the prism case for U = mach 3.and model as RNGkepsilon i am getting following wrror:

Aborted

Please help me in this respect.....
Thanks.

This message means, that your thermophysical model has failed while calculating temperature from enthalpy

review your boundary conditions and decrease time step (to meet requirement Co < 0.5)

thanks Matvaj,

i have reduced it and runthe case as will definately tell u once i run it

thanks a lot,

Hi Fomers,
this may look a begineers question but....
i have a problem here,
can anyone please tell me
1)how to calculate shock angle
2)and how to plot grad p over a wall
3)How to calculate wall shear stress

Please help me....

Regards

Vishal

Hi vishal,
perhaps you can describe your solution of the problem with the transportPropertiesDictionary. I have the same problem with rhoTurbFoam!

Thanks
