CFX User Guide query
In the ANSYS CFX-Solver Theory Guide (CFX Release 11.0) it gives the total energy equation on page 23 (eqn. 80). It's got the shear stress tensor (tau) in a dot product. I though this tensor was a vector, but the guide shows it as a scalar, it's not on bold like the other vectors. The same goes for the momentum and energy source terms.
These are vectors, right????
