Hello,
I am doing parametric study on my pipe geometry with venturi inside, my goal was to find the throat diameter which give me atmospheric pressure (101325 Pa). My first simulation ran smoothly and the solution converged as well. But for the design points further, I gave different Throat diameters for which i am getting same Pressure value as for my first simulation.

Please have a look on the screen shot attached under.

Can someone please suggest me anything?

That'll be the Teaching version: simply it's the University equivalent to Student.

The problem was the convergence checking in that version: it's been fixed. The best solution is to update to the latest version (2019R2) which you want to be using anyway as R17 is about 4 years old.
