【Need help】Pressure can't initialize ?
 

My model is a viscous damper.a rotor is working in a airtight space.All boundary conditions is no-slip Wall.

in Pressure-Based Solver ,I init the pressure by setting all-zones 2e5 Pa,but it doesn't work. While in Density-Based Solver ,it seems right. Why?

My work fluid is high viscous fluid,it's incompressible.
