I'm mouloud and I'm working in turbulent impinging jets on a cylinder.
I create my model 2D, when I use the normal model k epsilon it work,but the problem is the model in k-epsilon low number does not converge.
the message ereur is: singular matrix.
thank you

my graduation project is in ultrasonic flow meter,
can you give me some tutorials, how to make model and simulations
