Hi all,

I have defined a volSymmTensorField named tau1 and initialized with tau. tau is volSymmTensorField that is IOobject and has initial and boundary values in "0" folder. So the initial and boundary values of tau1 is the same as tau.
Now I want to change the values of the internal and boundary of tau1 like this:
forAll(tau1 , i)
     tau1[i].xy() = 40.5;
the internal values are changed, but the boundary values of tau1 are not changed!

What should I do?
