Boundary condition in laminar flow, Failed to consistent initial value

I have an static flow at initial time on the solid surface. After t=0; I should exert an external force to the fluid bulk so in this situation my fluid has a motion. Here because the down plate( solid surface) is cold plate so we have not natural convection. For solve my laminar flow equation what is my boundary conditions? I think because at first fluid is static so input and out put boundary condition is pressure (1 atm). I should say that when I write no slide wall for up and down boundary until about 10 N/m^3 flow equation can be solve but more than this value solver write that "Failed to consistent initial value".
Please any body can help me.
