Hello all
I am trying to change C1 coefficient for k-epsilon model in sprayFoam/constant/turbulensproperties file as follows:

simulationType RAS;

RAS
{
RASModel kEpsilon;

kEpsilonCoeffs
{
C1 1.52;
}

turbulence on;

printCoeffs on;
}

but it tells I don't have the permission to save the file!
Can anybody tell me how can I change C1?

indeed it works well, I was changing it in the main direction.
I had just copied the tutorial on the desktop, then I was able to define the coefficients as shown in the first post.
