Hi to all<\/p>\n

I am new to ANSYS CFX, and I’m trying to simulate the squish oil on simple geometry. I attached the geometry here. I’m using one sector of a cylinder. At first, I moved the bottom surface toward the upper surface about 0.08 mm ( all the thickness is 0.1 mm) and calculated the force on the upper surface, which was 0.66 N. So at the next step, I tried to impose this force on the bottom side to see if it reached the 0.08 mm displacement or not. Unfortunately, after a few time steps, the calculated force by the software reaches 0.66 N and starts to oscillate. My question is: shouldn’t force reach 0.66N when the displacement is 0.08mm? ( I used the unspecified option for side walls and opened with 0 Pa with unspecified walls.)<\/p>\n
