True-LDE is designed to make post processing Linear Dynamic Events intuitive and interactive. True-LDE leverages the power of linear superposition of modal results. Quickly probe the model for responses to user defined excitations. True-LDE offers powerful tools to create operating deflection shapes and peak value plots.


True-LDE interactive Linear Dynamic Event analysis supports:

  • Time Domain modal superposition

  • Deterministic Frequency Domain modal superposition

  • Random / PSD Domain modal superposition

With True-LDE the user can interactively create:

  • Nodal Functions

  • Elemental Functions

  • Full Field Results

Optionally include the effects of pre-load on all results.

Linear Dynamics is a critical part of understanding the real world response of structures.
The powerful FEA solutions of time domain, frequency domain, and PSD domain provide critical calculation results. Unfortunately, examining the results in an interactive fashion is challenging within most FEA post processors.


True-LDE solves this through an intuitive UI that allows the analyst to filter modes based on percent modal mass and modal participation function amplitude. The user can interactively query any node or element in the model for XY plots of the response.
In addition, full field results can be calculated for any subset of the time domain.


An important feature of True-LDE is that the effects of pre-load can be optionally included in any of the calculations. This feature is available for the interface to FEA based fatigue solvers as well. The influence of pre-load can be critical to the durability
of structures. No other linear dynamics tool provides an easy method for including
pre-load the way True-LDE does.
