How to understand the negative static pressure
 

Hello:
Theses days, I use one model to calculate the flow field. the boundary conditions are pressure-inlet and pressure-outlet. I found that there were some zones in which the negative static pressure is more than 1.5MPa.(the iterations are converged according to fluxes and residual curve) So I am confused

no one replies to it.

You can change the boundary conditions and try again.
