CFD not convergates at certain inlet pressures

Hello!
My name is Mark from the Technical University of Budapest. I would like to ask some help with my simulation.
I am modelling a 3D planar micro free-flow cell for separation with multiple inlets (and different initial velocities) using the Laminar flow module. The simulation runs prefectly if I definiate the inlet pressure as 10 Pa. If I would like to calculate the desired flow characteristics, I should set the inlet pressure to nearly 8000 Pa, but in this way the study didn't work, neither if I set the inlet velocities in m/s. The error doesn't convergate, and if yes (in some cases), only to a higher value (~10^2).
Thank you in advance for your answers and your help!
