Output of Frequency Analysis

After running a frequency study successfully, you can view:

  • Displacement

You can plot displacement components of resonant mode shapes:

  • UX = Displacement in the X-direction

  • UY = Displacement in the Y-direction

  • UZ = Displacement in the Z-direction

  • URES = Resultant displacement (does not use the reference geometry)

Mode shapes illustrate the profile of the mode only (i.e., the displacement of nodes relative to each other). The displacement values are calculated based on various normalization procedures. The software normalizes each mode shape such that { f i } T [M] { f i } is equal to [I]. Where { f i } is the vector representing the ith mode shape, { f i } T is its transpose, [M] is the mass matrix, and [I] is the unit matrix.

  • Deformation

You can plot the deformed shape of a particular mode. The corresponding frequency of the mode shape is shown on the plot. This is a shaded plot of the resultant displacement.

  • Report

You can create reports for the study.
