Web4 de abr. de 2024 · First, you are plotting an eigenvector. It is not an actual modal displacement, but rather a mode shape. If you want to see actual deflections, you need to do an expansion pass. See the MODOPT command. Second, the deflection results are likely scaled for plotting. You can use the /DSCALE command to change the plot scale.
