Sheila Guest Posts: n/a	Hi everyone, I am writing the k-w SST model in STAR as 2 scalars. I know that the model already exists in STAR but for my work I need to model them as separete quantities. At the moment one of te problems I am having is that the minimum value of my k is always a very small negative value rather than zero. Any idea on what I can do to make sure the minimum is zero? Thanks in advance for your help. Sheila
