Hello, I am new to comsol and i am working on reinforced concrete beam to analyse the displacement of the beam for 100Hz and 200 HZz frequency. The concrete beam is of 10*12 with steel reinforced. The beam is clamped on right and left side and the bounday load is given at the bottom(2000N/m2). The eigen frequency analysis shows diplacement in meters actually my displacement should be in microns. changing the boundary load seems no change in the displacement. Can anyone help me out with this.
