Every specialist: I tried many times and couldn't get a convergent result when I calculate just one row of turbine vane with tascflow. I used pressure inlet condition and pressure outlet condition, the outlet Mach number should be 1.05 if it's convergent. How should I set up this problem?

thanks advance.

(1). Try to lower your exit Mach number first. (2). Run another case, to see whether you can get the flow field to converge at a lower Mach number. (3). If you still have problem, check with the support engineer.
